Project and system firm capacity definitions with long term hydro scheduling 项目和系统确定长期水电调度的容量定义
E. Hreinsson
In a hydro-dominated power system, with complex inter-temporal linkages, capacities of individual projects and project configurations are more complicated than using the simple megawattage, often used to denote capacity in thermally dominated systems. In this paper, the long term hydro scheduling problem is solved and used to test novel definitions of hydro-capacities, based on expected cost and cost probability distributions for system operating cost, based on rising load and a within-the-year time distribution of load. The paper expands on previous capacity definitions and tests them numerically in a case study with realistic data from a hydro-dominated system. The principal contribution of this paper are new capacity concepts and practical applications for an example of sizing a given reservoir. The testing is performed using actual data from the Icelandic hydro-dominated power system, with the model HYDOVG delivering optimal schedules for various inflow instances and load cases and using linear programming (LP) CPLEX software to optimize each case and instant.
在水力主导的电力系统中,具有复杂的跨时间联系,单个项目的容量和项目配置比使用简单的兆瓦数更为复杂,兆瓦数通常用于表示热主导系统的容量。本文解决了长期水力调度问题,并将其用于测试基于系统运行成本的预期成本和成本概率分布、基于负荷上升和负荷年内时间分布的水力容量的新定义。本文对以前的容量定义进行了扩展,并在一个水力控制系统的实际数据的案例研究中对它们进行了数值测试。本文的主要贡献是新的容量概念和实际应用的一个例子的规模给定的油藏。测试使用了冰岛水力发电系统的实际数据,HYDOVG模型为各种流入实例和负载情况提供了最佳调度,并使用线性规划(LP) CPLEX软件对每种情况进行优化。

E. Abbasi, S. H. Hosseini, M. D. Ghamsari
In this paper a reliability, emission, and network security constrained unit commitment (UC) with the focus on wind power integration is formulated. It is shown that clearing both energy and spinning reserve markets taking into account network constraints provides a reliable and economic solution for day-ahead operation planning of a power system with a significant amount of thermal and wind power in the generation portfolio. The developed UC is formulated and implemented in MATLAB. The IEEE 24-Bus Reliability Test System (RTS) is used to verify the UC method by simulation.

Evaluating PEV's impact on long-term cost of grid assets 评估PEV对电网资产长期成本的影响
Daijiafan Mao, D. Meyer, Jiankang Wang
With increasing penetration and improving fast charging technologies, Plug-in Electric Vehicles (PEV) exert a disruptive influence on power delivery systems. The impulsive and high-power-density characteristics of PEV make conventional assessment methods of load impact unsuitable. This paper proposes an integrated method to investigate the long-term impact of PEV charging on temporal response and depreciation of grid assets in sub-transmission and distribution grid levels (below 69kV). Compared to conventional methods, the proposed method embeds dynamical system models of grid assets in Time-Series (TS) analysis and captures stochastic charging behavior through Monte-Carlo simulation, promising more robust and accurate assessment. Under the proposed method, the Total Cost of Ownership (TCO) of grid assets formulation is re-established. The results of this paper will enable utilities to quantify the capital and operation cost of grid assets induced under various PEV's penetration level and during any time span of interest.
随着快速充电技术的日益普及和改进,插电式电动汽车(PEV)对电力输送系统产生了颠覆性影响。电动汽车的脉冲特性和高功率密度特性使得传统的负荷冲击评估方法不适用。本文提出了一种综合方法,研究电动汽车充电对分输配电网(69kV以下)电网资产时间响应和折旧的长期影响。与传统方法相比,该方法将电网资产的动态系统模型嵌入到时间序列分析中,并通过蒙特卡罗模拟捕捉随机充电行为,具有更强的鲁棒性和准确性。在该方法下,重新建立了电网资产形成的总拥有成本(TCO)。本文的结果将使公用事业公司能够量化在不同PEV渗透水平和任何感兴趣的时间范围内引起的电网资产的资本和运营成本。

Optimal PMU placement to achieve complete observability of Idaho Power Co. System 最佳PMU放置,以实现爱达荷电力公司系统的完全可观察性
O. Ciniglio, M. Papic, M. Vaiman, M. Vaiman
This paper presents an effective practical approach for identifying optimal locations of Phasor Measurement Units (PMUs) to achieve complete system observability. The approach, implemented in Physical and Operational Margins/Region Of Stability Existence (POM/ROSE) software, is based on automated iterative process of forming variables and constraints of a binary integer programming problem. The problem is then solved with standard linear programming solvers. The proposed approach was tested using Idaho Power Co. (IPC) system. It allows us to reduce the number of PMUs as compared to conventional techniques while maintaining complete system observability. A fast topological approach was also demonstrated and tested using IPC data in order to analyze the observability of the IPC network. The algorithm is fast and can be used in real-time as a part of bad data detection framework.

Local detection of PMU measurement errors using dynamic state estimators 基于动态估计器的PMU测量误差局部检测
A. Rouhani, A. Abur
This paper proposes the use of a couple of local PMUs and associated dynamic state estimators in order to detect and remove bad data in PMU measurements. Distinguishing features of the proposed approach is that it facilitates detection of bad-data in local PMU measurements without requiring a system-wide state estimator. The proposed approach relies on a performance evaluation technique which computes the probability density function (pdf) of the residuals provided by a dynamic state estimator. In the proposed approach it is assumed that there are at least two local PMUs that provide measurements to the dynamic state estimators of a synchronous generator. The proposed approach is implemented using a two-axis model of a synchronous generator with IEEE-Type 1 exciter. The performance of the proposed approach is investigated in the presence of bad-data associated with the measurements provided by the PMUs.
为了检测和去除PMU测量中的不良数据,本文提出了使用一对局部PMU和相关的动态估计器。该方法的显著特点是,它有助于检测局部PMU测量中的坏数据,而不需要系统范围的状态估计器。所提出的方法依赖于一种性能评估技术,该技术计算由动态估计器提供的残差的概率密度函数(pdf)。在提出的方法中,假设至少有两个本地pmu为同步发电机的动态状态估计器提供测量。采用带ieee - 1型励磁器的同步发电机双轴模型实现了该方法。在与pmu提供的测量相关的坏数据存在的情况下,研究了所提出方法的性能。

Design and development of a microgrid control system for integration of induction generation with storage capability at Saint Paul Island, Alaska 阿拉斯加圣保罗岛感应发电与储能集成微电网控制系统的设计与开发
A. Khatib, B. Nayak, Bowen Dai, Jito Coleman, S. Hoskins, Jan Tierson
This paper presents a centralized microgrid control system for effective operation of wind turbines and diesel engines coupled to a flywheel electrical storage component on Saint Paul Island. The wind turbines have sufficient capacity to support the entire island without using the diesel engines, allowing the formation of an islanded power system completely powered by renewables. The proposed strategy includes use of the flywheel, wind turbines, and diesel generators to attain survivability and resilience. The strategy is challenged and validated against different low to turbulent wind gust profiles and low to peak loading. Multiple permissive-based decoupling schemes, tie-flow controls, and heat load trading features are implemented. The tie-line flow control/heat load trading is operated in tandem with local diesel generators and wind turbines to maintain a minimum flow from the utility. The control system was tested using hardware-in-the-loop (HIL) with a simplified electrical model of Saint Paul Island.

Empirical analysis of convergence and sensitivity of demand response based on real time pricing 基于实时定价的需求响应收敛性和敏感性实证分析
Smita Lokhande, Y. Bichpuriya
Increasing penetration of intermittent renewable energy at distributed and bulk generation level introduces challenges in maintaining supply-demand balance in the electric grid. To achieve demand-following-generation regime, it is important to utilize flexibility of demand by direct or indirect control. It is referred as Demand Response (DR). Indirect control involves incentives or variable prices in different time blocks to bring the aggregated demand at a desired level. In a market scenario, demand and price are mutually dependent variables, i.e., demand can affect the price and vice-versa. In this paper, we present an empirical analysis of demand response based on real time pricing. The analysis is done to study the convergence of the demand in a closed loop market scenario and sensitivity of DR with varying price elasticity.

Short-term state forecasting-based optimal voltage regulation in distribution systems 基于短期状态预测的配电系统最优电压调节
Rui Yang, Huaiguang Jiang, Y. Zhang
A novel short-term state forecasting-based optimal power flow (OPF) approach for distribution system voltage regulation is proposed in this paper. An extreme learning machine (ELM) based state forecaster is developed to accurately predict system states (voltage magnitudes and angles) in the near future. Based on the forecast system states, a dynamically weighted three-phase AC OPF problem is formulated to minimize the voltage violations with higher penalization on buses which are forecast to have higher voltage violations in the near future. By solving the proposed OPF problem, the controllable resources in the system are optimally coordinated to alleviate the potential severe voltage violations and improve the overall voltage profile. The proposed approach has been tested in a 12-bus distribution system and simulation results are presented to demonstrate the performance of the proposed approach.

Optimal energy scheduling of a stand-alone multi-sourced microgrid considering environmental aspects 考虑环境因素的单机多源微电网最优能源调度
H. Moradi, D. D. Groff, A. Abtahi
A standalone microgrid with renewable and regular power resources along with storage system play an important role in remote areas in order to solve power supply problems. In this research, an optimal energy management of a standalone microgrid under different operational modes is studied. The objective of the optimization model is to improve energy utilization efficiency; reduce fuel cost and gas emissions by scheduling productions of energy resources in each hour on the next day. In another word, the problem is modeled as a constrained single-objective programming to minimize cost of power and emission generations. The system is tested under two different operational policies where microgrid power generation sources work with and without battery storage system. Then the final results are compared and investigated. The results show a considerable reduction in system total cost and generated emission in comparison with previously proposed methods.

Design of an adaptive sending rate for frequency regulation of a smart microgrid with optimal LQR controller 基于最优LQR控制器的智能微电网调频自适应发送速率设计
F. Mohammadi, H. Keshtkar, A. Feliachi, V. Kulathumani
This paper is on the design of an adaptive sending rate for frequency regulation of a smart microgrid. The frequency controller itself is designed using an optimal LQR (Linear Quadratic Regulator) approach whose parameters are obtained using Particle Swarm Optimization (PSO). The utilized isolated smart microgrid comprises different Distributed Generation (DG) units and Renewable Energy Sources (RESs). Implementation of the optimal LQR controller requires a communication network. The key issue in this Networked Control System (NCS) is the transmission of measured data from the multiple sensing agents to the controller. Usually the data is sent in constant intervals which raises energy issues and channel capacity and requires bigger sending rate that will cause more error in the frequency response.

本文研究了智能微电网频率调节的自适应发送率的设计。频率控制器本身采用最优LQR(线性二次型调节器)方法设计,其参数采用粒子群优化(PSO)获得。所使用的隔离式智能微电网由不同的分布式发电(DG)单元和可再生能源(RESs)组成。实现最优LQR控制器需要一个通信网络。该网络控制系统(NCS)的关键问题是将测量数据从多个传感代理传输到控制器。通常数据以恒定的间隔发送,这会引起能量问题和信道容量,并且需要更大的发送速率,这将导致频率响应中的更多误差。本文提出了不同的自适应方法来确定适当的发送速率。仿真结果表明,与传统方法相比,所提方法是有效的。

The frequency controller itself is designed using an optimal LQR (Linear Quadratic Regulator) approach whose parameters are obtained using Particle Swarm Optimization (PSO). The utilized isolated smart microgrid comprises different Distributed Generation (DG) units and Renewable Energy Sources (RESs). Implementation of the optimal LQR controller requires a communication network. The key issue in this Networked Control System (NCS) is the transmission of measured data from the multiple sensing agents to the controller. Usually the data is sent in constant intervals which raises energy issues and channel capacity and requires bigger sending rate that will cause more error in the frequency response. The paper proposes different adaptive approaches for determining an adequate sending rate. Simulation results show the effectiveness of the proposed approaches as compared to conventional methods.","PeriodicalId":296398,"journal":{"name":"2017 IEEE Power & Energy Society Innovative Smart Grid Technologies Conference (ISGT)","volume":"33 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122238095","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
