This paper relates the experience of use of the optimal power flow software IPSO (integrated power system optimizer) for solving problems related to the Belgian power system short term operation and planning. The optimization is performed using the KNITRO solver based on an interior point algorithm. After a short description of the main algorithm features, the paper focuses on the utilisation of OPF program to solve two main optimization problems typical of the operation of the Belgian grid system that is highly interconnected to the UCTE grid: a/ the evaluation of the steady state TTC (total transfer capability) which is a key component of the ATC (available transfer capability) provided to the market operators and the quantification of the TRM (transfer reliability margin) b/ the supervision of the tertiary voltage control (TVC) that implements the maximization of the units individual reactive power margin through the emulation of the highly customized linear programming algorithm implemented within the EMS software for operational or planning purposes

Applications of network control devices such as phase shifting transformers and flexible AC transmission system (FACTS) devices in power systems include congestion management and parallel flow reduction. In a market environment, it is common for these devices to be primarily operated for local congestion relief. However, this single objective control may not utilize the controller to its maximum extent. It may be possible for the device to both manage congestion and reduce parallel flow. This paper develops a two-level hierarchical multiobjective optimization method that determines the operating points of an area's network control devices for local congestion management and inter-area parallel flow reduction, as measured by a novel wide-area impact index. This index is comprised of the weighted sum of the changes in line flow over a large number of transmission lines caused by the operation of an adjacent area. The method and index are validated through an application to a 30-bus test system
移相变压器和柔性交流输电系统(FACTS)等网络控制设备在电力系统中的应用包括拥塞管理和减少并联流。在市场环境中,这些设备通常主要用于缓解局部拥塞。然而,这种单一目标控制可能无法最大限度地利用控制器。设备可以同时管理拥塞和减少并行流。本文提出了一种两级分层多目标优化方法,该方法确定了区域网络控制设备的工作点,用于局部拥塞管理和区域间并行流量减少,并通过一种新的广域影响指数来衡量。该指标由相邻区域运行引起的大量输电线路的线流变化的加权和组成。通过30总线测试系统的应用验证了该方法和指标的有效性

Congestion management in Japan 日本的交通拥堵管理
Pub Date : 2005-11-21 DOI: 10.1109/CIGRE.2005.1532721

There are 10 regional Vertical Integrated Utilities in Japan, and these operate the individual regional systems. The tile-lines between adjacent utilities are used supplementary. On the other hand, Japan has stepped into next stage in its liberalization, and since April 2005 the customers who consume about 60% of total sales can choose their suppliers. There are two noteworthy elements in Japanese liberalization: a neutral organization and a wholesale power exchange. The neutral organization is unique, neither a regulator nor a system operator. The players in Japan's liberalization scheme discussed and published rules for tie-line use. There are two principles for tie-line use in Japan, upon which congestion management is based: "first come, first served," and "use it or lose it." The grid users do not need to pay for tie-line capacity allocation, but they need to pay a charge for the certain change of their plans posted to prevent intentional overestimates of capacity needs
日本有10个地区垂直综合公用事业公司,它们运营着单独的地区系统。相邻公用设施之间的瓷砖线是补充使用的。另一方面,日本已经进入了自由化的下一个阶段,从2005年4月开始,消费总销售额约60%的客户可以选择他们的供应商。日本的自由化有两个值得注意的因素:中立组织和批发电力交换。中立组织是独特的,既不是监管者也不是系统操作员。日本自由化计划的参与者讨论并公布了领带使用规则。在日本,交通拥堵管理基于两个原则:“先到先得”和“要么用,要么丢”。电网用户不需要为联络线容量分配付费,但他们需要为公布的计划的某些更改付费,以防止故意高估容量需求

Firm transmission rights (FTRs) are issued by TSOs and can be bought by market operators in order to hedge the risk connected to the volatility of price differentials in a zonal market. FTRs are typically defined w.r.t. a couple of zones; their owners have the right or the obligation (depending on the nature of the title) to receive back from the TSO an amount of money equal to the difference between the prices in the "downstream" and "upstream" zones times the quantity object of the right. The aim of the paper is to assess these consequences, in particular concerning the issue of revenue sufficiency and the possibility that generators with market power owning FTRs may dispose of enhanced gaming opportunities in the Italian energy market
公司传输权(ftr)由tso发行,市场经营者可以购买,以对冲与区域市场价差波动相关的风险。ftr通常在几个区域内定义;其所有者有权或有义务(取决于所有权的性质)从TSO收到一笔等于“下游”和“上游”区域价格之差乘以权利数量对象的金额。本文的目的是评估这些后果,特别是关于收入充足的问题,以及拥有ftr的市场力量的发电机可能会在意大利能源市场上处理增加的游戏机会的可能性

Identification of transmission line user and congestion management by loop flow controllers 传输线用户识别与环路流控制器的拥塞管理
Pub Date : 2005-11-21 DOI: 10.1109/CIGRE.2005.1532756

The deregulation of electric power industry has been proceeding in Japan. Some new comers' can use traditional power utilities' transmission lines under proper rules. In this situation, a question: "Who use individual transmission lines" has become an important concern. Since an organization like ISO or RTO has to manage the congestion and has to charge proper transmission fee to users. The loop flow control by DC-link and phase-shifter (UPFC) is also essential issue. A system operator has to obey proper control rules which should be fair and equal to all related members. In this paper, a simple algorithm has been proposed to identify the transmission users in the third party access. This algorithm is based on "DC-flow" approach, which treats only the injection power (P) and the voltage phase angle (delta). DC-link, phase shifter and switching of CB can control loop flows. Every loop flow controller can be modeled as pseudo power injections at both "from" and "to" nodes of each controller. These injections have same absolute values with opposite sign. The effects of controllers can be identified and isolated independently from other load flows. In this paper, two steps of loop flow control have been discussed. In the first Control-1, a system operator adjusts the loop flow controllers using an optimization method based on LP or QP. These control action does not affect to energy balance in each company. In the second Control-2, a system operator indicates required modifications of line flows to each company so as they can change their energy balance by themselves. Although we could not complete numerical tests in this stage, we check the performance in near future using larger test cases
日本一直在推进对电力行业的放松管制。一些新来者可以在适当的规则下使用传统电力公司的输电线路。在这种情况下,一个问题:“谁使用单独的传输线”已经成为一个重要的问题。因为像ISO或RTO这样的组织必须管理拥塞,并且必须向用户收取适当的传输费用。通过直流链路和移相器(UPFC)控制环路流量也是一个关键问题。系统操作员必须遵守适当的控制规则,这些规则对所有相关成员都应该是公平和平等的。本文提出了一种简单的算法来识别第三方接入中的传输用户。该算法基于“直流流”方法,只处理注入功率(P)和电压相角(delta)。直流电路、移相器和CB开关可以控制环路流量。每个环流控制器都可以建模为每个控制器的“from”和“to”节点上的伪功率注入。这些注入的绝对值相同,但符号相反。控制器的影响可以独立于其他负载流进行识别和隔离。本文讨论了循环流量控制的两个步骤。在第一个Control-1中,系统操作员使用基于LP或QP的优化方法调整环路流量控制器。这些控制措施不影响每个公司的能量平衡。在第二个控制-2中,系统操作员向每个公司指示需要修改的线路流,以便他们可以自己改变他们的能量平衡。虽然我们不能在这个阶段完成数值测试,但我们将在不久的将来使用更大的测试用例检查性能

This paper thoroughly investigates how best it would be to send an adequately accurate locational price signal with the congestion costs incorporated into the transmission pricing rule when the electricity market, in which costs are recovered from all transmission users on an equivalent basis, is not unduly maintained. This paper attempts to make a supportive and self-explanatory proposal that it could fit the Korean cost-based pool (CBP) that satisfactorily sharpens the locational price signal.

Properly applied, information technology can go a long way to meet challenges introduced by the changes in power flow introduced by the opening of electricity markets. To provide efficient support to utilities information systems must be well adapted to current and future business needs. For some years the goal of information systems support at utilities have been an integrated suite of IT systems that are well aligned to the business processes. This, to some extent Utopian, goal is sometimes referred to as the integrated utility. This paper presents experiences with applying a modelling approach, using established notation and standards that can be used to analyze utility-wide information system architectures. The specific characteristic of the modelling approach presented in this paper is that the modelling is done with the IEC standardised common information model as a basis. The benefits of using the approach is that it provides a straightforward method to create consistent documentation of use of data and functionality across several systems. The output created consist of unambiguous UML compliant models, and standards based functionality listings in which data and functionality duplication and overlap can be identified. The paper is concluded with a presentation of a case study in which the proposed approach was applied to a real world utility's business processes and systems. The case study shows promising results for the approach, but also underlines the need for further work
如果应用得当,资讯科技可以在很大程度上应对电力市场开放所带来的潮流变化所带来的挑战。为了向公用事业提供有效的支援,资讯系统必须能够很好地适应当前和未来的业务需要。多年来,公用事业公司的信息系统支持目标一直是与业务流程保持良好一致的IT系统集成套件。在某种程度上,这种乌托邦式的目标有时被称为综合效用。本文介绍了应用建模方法的经验,使用可用于分析公用事业范围的信息系统体系结构的已建立的符号和标准。本文提出的建模方法的具体特点是以IEC标准化公共信息模型为基础进行建模。使用这种方法的好处是,它提供了一种直接的方法来创建跨多个系统的数据和功能使用的一致文档。创建的输出由明确的UML兼容模型和基于标准的功能列表组成,其中可以识别数据和功能的重复和重叠。本文最后给出了一个案例研究,在这个案例研究中,所建议的方法被应用到一个现实世界的公用事业的业务流程和系统中。案例研究显示了该方法的良好结果,但也强调了进一步工作的必要性

Coordinated auction project in Central Europe 协调中欧拍卖项目
Pub Date : 2005-11-21 DOI: 10.1109/CIGRE.2005.1532739
P. Sole
The demand for capacity reservations at the transmission interconnections between control areas in Central Europe is usually much higher than the capacity available for electricity trading. It is expected, that as a consequence of market opening according to the market liberalisation in Europe, the demand will further increase over time. In the beginning of 90th, before liberalisation of electricity market, there were vertically integrated utilities - monopolies in each of Central European countries. Cross border exchange was mainly between two utilities, and only as an addition to the overall national balance. Utilisation of interconnectors was planned together with system balance planning and there was under normal operation no congestions. Since 2002, demand for cross border capacity exceeded permanently offered capacities. Congestion management methods was gradually developed on different interconnectors depend on the level of electricity market opening in different states. The vast majority of electricity trading in control areas of concerned TSOs is thus based on OTC bilateral contracts. For that reason, explicit auctions was established as the most appropriate market mechanism for cross border capacity allocation. First auctions was organized independently on both sides of the interconnection i.e. two auctions for one interconnection. Soon after, under the pressure from traders side, concerned TSOs established on most of the interconnectors common bilateral auction. Due to the technical constrains in the regional network there are two possible technical limits, which must be taken into account. Either the internal network in one control area is congested as a consequence of the past development. Concerned TSO's in the region agreed to start a common regional auctioning procedure for transmission capacities reservation on all borders between them in the same time and to allocate available capacities on the congested profiles in the way which gives to market players a requested transmission capacity reservation on the indicated border .

中欧控制区之间输电互连的容量预留需求通常远高于电力交易的可用容量。预计,随着欧洲市场自由化的开放,需求将随着时间的推移进一步增加。90年代初,在电力市场自由化之前,中欧各国都存在垂直整合的公用事业垄断。跨境交换主要是在两家公用事业公司之间进行的,只是作为对国家总体平衡的补充。互连线的使用已与系统平衡规划一起规划,在正常运作下没有拥塞。自2002年以来,对跨境运力的需求超过了永久提供的运力。根据各州电力市场开放程度的不同,在不同的互联网络上逐步发展出拥堵管理方法。因此,在有关电力服务公司的管制区内,绝大多数电力交易都是基于场外交易双边合约。因此,明确拍卖是跨境产能配置最合适的市场机制。第一次拍卖是在互联的双方独立组织的,即一次互联的两次拍卖。不久之后,在贸易商方面的压力下,有关的贸易商组织在大多数互连点上建立了共同的双边拍卖。由于区域网络的技术限制,有两种可能的技术限制,必须加以考虑。一个控制区域的内部网络由于过去的发展而变得拥挤。该地区有关的TSO同意在同一时间启动一个共同的区域拍卖程序,以保留它们之间所有边界的传输容量,并以向市场参与者提供指定边界上请求的传输容量预留的方式,在拥挤的剖面上分配可用容量。2005年的年度、月度和每日容量拍卖在每月拍卖之后举行。日常拍卖和市场参与者之间的容量转移是通过拍卖电子门户网站进行管理的

It is expected, that as a consequence of market opening according to the market liberalisation in Europe, the demand will further increase over time. In the beginning of 90th, before liberalisation of electricity market, there were vertically integrated utilities - monopolies in each of Central European countries. Cross border exchange was mainly between two utilities, and only as an addition to the overall national balance. Utilisation of interconnectors was planned together with system balance planning and there was under normal operation no congestions. Since 2002, demand for cross border capacity exceeded permanently offered capacities. Congestion management methods was gradually developed on different interconnectors depend on the level of electricity market opening in different states. The vast majority of electricity trading in control areas of concerned TSOs is thus based on OTC bilateral contracts. For that reason, explicit auctions was established as the most appropriate market mechanism for cross border capacity allocation. First auctions was organized independently on both sides of the interconnection i.e. two auctions for one interconnection. Soon after, under the pressure from traders side, concerned TSOs established on most of the interconnectors common bilateral auction. Due to the technical constrains in the regional network there are two possible technical limits, which must be taken into account. Either the internal network in one control area is congested as a consequence of the past development. Concerned TSO's in the region agreed to start a common regional auctioning procedure for transmission capacities reservation on all borders between them in the same time and to allocate available capacities on the congested profiles in the way which gives to market players a requested transmission capacity reservation on the indicated border .

ETSO, European Transmission System Operators, was founded in 2001 and is composed of European TSOs also members from UCTE (Union pour la Coordination du Transport de l'Electricite), Nordel (Nordic Countries Association), UKTSOA (UK) and ATSOI (Ireland). The opening of the European electricity market requires a considerable amount of electronic data interchanges (EDI) between all market participants. Consequently ETSO Task Force 14 was set up in order to harmonise EDI and especially the documents to be exchanged. This paper has the following objectives: 1) to provide an overview of the ETSO standards, 2) to provide a situation report on the actual European implementation of the ETSO standards, 3) to present the ongoing activities of ETSO TF 14
欧洲输电系统运营商(ETSO)成立于2001年,由欧洲输电系统运营商以及来自UCTE (Union pour la Coordination du Transport del’electricite)、Nordel(北欧国家协会)、UKTSOA(英国)和ATSOI(爱尔兰)的成员组成。欧洲电力市场的开放需要所有市场参与者之间进行大量的电子数据交换(EDI)。因此,成立了ETSO第14工作队,以便协调电子数据交换,特别是要交换的文件。本文的目的如下:1)提供ETSO标准的概述,2)提供欧洲实际实施ETSO标准的情况报告,3)介绍ETSO TF 14正在进行的活动
