Programmable load emulator is used for implementation and analysis of different electrical load change scenarios in power electronics and microgrid laboratory researches. Load emulators usually use PI controllers to track the reference active and reactive power profiles. PI controller coefficients depend on operating point therefore it is not suitable especially for this application in which the operating point is constantly changing in a wide range. Also in microgrid laboratory researches, because of low inertia, the voltage and frequency variations are considerable which can effect on load emulator operation. In this paper, a fuzzy-based PI controller is presented for a chopper-based load emulator in AUT microgrid for both islanding and grid connected operation modes. Experimental results show the performance of the fuzzy system in comparison to conventional PI controller for load emulator in both operation modes.
可编程负载仿真器用于电力电子和微电网实验室研究中不同负荷变化场景的实现和分析。负载模拟器通常使用PI控制器来跟踪参考有功和无功功率配置文件。PI控制器系数依赖于工作点,因此不适用于工作点在大范围内不断变化的应用。同样在微电网的实验室研究中,由于微电网惯量小,电压和频率变化较大,影响负载模拟器的运行。本文提出了一种基于模糊PI控制器的基于直升机的AUT微电网负荷仿真器,适用于孤岛和并网两种运行模式。实验结果表明,在两种工作模式下,模糊控制系统的性能都优于传统的PI控制器。

Due to the small capacity of DGs, their individual participation in the energy market is not beneficial. In the case of wind and solar plants, their uncertain power generation is another issue for their participation in the market, especially when their capacity is low. Commercial Virtual Power Plant (CVPP) is a new market participant, which represents a group of various DGs in the market, and bids to the market. This paper proposes a new bidding strategy approach for the participation of CVPP in the day-ahead energy market, considering uncertainties of wind turbine generation and Market Clearing Price (MCP). The market is pay as bid, and each participant bids a multi-step price-power curve. The uncertainty of MCP has formulated analytically, while the wind uncertainty is modeled by a quantized Rayleigh probability distribution function. Particle Swarm Optimization (PSO) algorithm is utilized for optimizing the objective function, which is the expected benefit of the CVPP. Numerical results are provided to evaluate the performance of proposed approach in increasing the benefit of VPP.
由于dg的容量小,他们单独参与能源市场是没有好处的。以风能和太阳能发电厂为例,它们发电的不确定性是它们参与市场的另一个问题,尤其是在它们的产能较低的情况下。商业虚拟电厂(CVPP)是一种新的市场参与者,它代表了市场上各种虚拟电厂的组合,并向市场投标。考虑风力发电的不确定性和市场出清价格(MCP)的不确定性,提出了一种新的CVPP参与日前能源市场竞价策略方法。市场是按出价付费的,每个参与者都出价一步一步的价格-能力曲线。MCP的不确定性用解析式表示,风的不确定性用量子化的瑞利概率分布函数表示。利用粒子群优化算法对目标函数进行优化,实现了CVPP的预期效益。数值结果验证了该方法在提高VPP效益方面的性能。

The use of power electronic converters for connection to the grids is causing harmonics. In this paper, for elimination of harmonics and increasing the quality of the voltage and output current of inverter, a three-level inverter is used, which connects micro-grid to a commercial electric power distribution system (utility one). An adaptive fuzzy PI controller was also used to control it, which then has a high pace of reply with a good performance in sudden changes of loads. The performance of micro grid in case of faults from utility grid was also analyzed. In this condition, the micro grid is disconnected from utility grid and act islanded. The connection and disconnection act of micro grid from the utility grid should happen rapidly. A simple method with a high speed is presented for this purpose. In the presented method, voltage domain and phase angel of both grids are compared. In case of outgoing of synchronism mode, micro grid is disconnected from the grid. The reconnection of micro grid happens when it is synchronized with the utility grid. Simulation results declare the accuracy of the proposal method.

In this paper, a nonlinear multivariate model for wind turbines is considered. Due to the increasing need for energy and limitation in fossil fuels, wind speed turbines vary widely, despite their high costs in power plants, so it is essential to achieve maximum efficiency and maintain their sustainability. For this purpose, a variable speed winding turbine system is modeled with a dual power generator modeled in this uncertain system, such as variations in wind speed and uncertainty in modeling and parameter values. In order to improve the behavior of system outputs in the unstructured presence of uncertainties, a controller is designed using a sliding mode of the terminal to reduce the system shifting by combining the adaptive modeling theory to deal with the indeterminate parameters and control signal smoothing. In this method, the combination of interest is designed adaptively, and is independent of the boundary of the indefinite and independent determinants. Finally, simulation of the results has been done using MATLAB software. The simulation results show the proper performance of the proposed controller in an uncertain presence compared to other methods.
本文考虑了风电机组的非线性多变量模型。由于能源需求的增加和化石燃料的限制,风力涡轮机的速度变化很大,尽管它们在发电厂中的成本很高,因此实现最大效率和保持其可持续性至关重要。为此,采用双功率发电机对变速绕组涡轮系统进行建模,该系统存在风速变化、建模和参数值的不确定性等不确定因素。为了改善系统在非结构化不确定性存在下的输出行为,结合自适应建模理论处理不确定参数和控制信号平滑,设计了一种利用终端滑模来减少系统移位的控制器。该方法自适应地设计了兴趣组合,并且不依赖于不定行列式和独立行列式的边界。最后,利用MATLAB软件对结果进行了仿真。仿真结果表明,与其他方法相比,所提出的控制器在不确定情况下具有良好的性能。

One of the main problems in the islanded microgrids is the frequency regulation. Moreover, there are several uncertainties and disturbances in the islanded microgrids that may lead to the instability. To solve this problem, this paper proposes the design of a multi-objective Linear Matrix Inequalities (LMIs) based regulator. It considers the LMI conditions in such a way that the design criterion holds. It also considers the disturbances, including solar radiation, wind speed, and load demand variations. With extracting microgrid state space model, it builds a framework to synthesize the controller. Next, it presents the mixed robust design criteria to set up the multi-objective function. The controller design process includes two steps: state feedback and observer designs. With considering weighing functions in the design process, it determines the optimal solution of the objective function. The obtained solution is the state feedback matrix, and it forms the controller by combining the state feedback matrix with a state observer. We have applied the designed controller to the islanded microgrid, and the effect of disturbances is evaluated together with parametric uncertainties. The proposed regulator is compared with the traditional PI method. The results show that the designed regulator has robust performance as well as robust stability.
孤岛微电网的主要问题之一是频率调节。此外,孤岛微电网中存在一些不确定因素和干扰,可能导致系统不稳定。为了解决这一问题,本文提出了一种基于多目标线性矩阵不等式(LMIs)的调节器设计。它考虑LMI条件的方式符合设计准则。它还考虑了干扰,包括太阳辐射、风速和负荷需求变化。在提取微网状态空间模型的基础上,构建了控制器综合框架。其次,提出了建立多目标函数的混合稳健设计准则。控制器设计过程包括状态反馈和观测器设计两个步骤。在设计过程中考虑权重函数,确定目标函数的最优解。得到的解为状态反馈矩阵,将状态反馈矩阵与状态观测器结合构成控制器。将所设计的控制器应用于孤岛微电网,并对扰动和参数不确定性的影响进行了评估。并与传统的PI方法进行了比较。结果表明,所设计的调节器具有鲁棒性能和鲁棒稳定性。

Optimization of cost functions along with control systems is a very significant issue in smart grids. In this paper, two novel control laws are designed to control photovoltaic system using Voltage Source Converter (VSC) model. The proposed control method is created by incorporating the optimization method, Linear Quadratic Regulator (LQR), and the Terminal Sliding Mode Control (TSMC) scheme, along with estimation of upper bound of system's uncertainties by adaptive concept. Then, numerical simulation is carried out by using MATLAB Simulink environment to verify the effectiveness of designed control laws in this note. At the end, a comprehensive comparison is provided to compare these two control laws from various aspects. Some of the key features of the proposed controllers are the robustness against a variety of uncertainties and external disturbances, as well as the finite time stability and Chattering-free.

Renewable energy sources, propagation and extension in the world put its undeniable effects on electricity consumers, which supplies many homes, and buildings equipped with Photovoltaic (PV) system as one of the distributed energy resources (DERs). Due to PVs generation uncertainty and the necessity of energy economy management in the buildings, an optimal energy management method is needed that should be implemented based on the user critical load demand response with considering the storage capacity. This paper addresses a smart load management approach based on State of Charge (SOC) index to determine battery capacity in the condition of the PV generation uncertainty at 24 hours a day in the island state. It should be noticed that in the current load management method in the similar conditions the customers dealt with a power outage because the distribution network and customer devices will be protected from voltage fluctuation. The customer dissatisfaction and power generation uncertainty are the significant disadvantages of it. For this reason, to find a solution regard to smart demand response, it is suggested that the residential critical loads, categorized in three groups in which based on the smart selective program the target cluster loads supplied. According to the mentioned approach, 62% and 54% of winter and summer critical loads with considering the battery capacity in the island system are supplied, respectively. Furthermore, each electricity consumer average revenue in the condition of the PV generation uncertainty as the worst case (island state) are increased 1.93 $ and 2.91 $, respectively.
可再生能源在世界范围内的传播和扩展对电力消费者产生了不可否认的影响,它为许多家庭提供电力,而安装光伏(PV)系统作为分布式能源(DERs)之一的建筑物。由于光伏发电的不确定性和建筑节能管理的必要性,需要一种基于用户临界负荷需求响应并考虑存储容量的最优能源管理方法。本文研究了一种基于荷电状态(SOC)指数的智能负载管理方法,以确定该岛24小时光伏发电不确定条件下的电池容量。值得注意的是,在目前的负荷管理方法中,在类似的情况下,由于配电网和客户设备将免受电压波动的影响,客户处理停电。客户的不满意和发电的不确定性是其显著的缺点。因此,为了寻找智能需求响应的解决方案,建议将住宅临界负荷分为三组,其中基于智能选择方案的目标集群负荷提供。根据上述方法,在考虑海岛系统电池容量的情况下,分别提供冬季和夏季临界负荷的62%和54%。此外,在光伏发电不确定性为最坏情况(岛国)的情况下,每个电力消费者的平均收益分别增加1.93美元和2.91美元。

This paper suggests a methodology for Phasor Measurement Units (PMUs) optimum placement for State Estimation (SE) with regard to double contingency. Firstly, SE problem is converted into the optimization one where the fitness function is the number of unobservable nodes that is specified on the basis of Singular Value Decomposition (SVD). In the regular condition, Differential Evolution (DE) method is utilized to discover the optimum PMUs placement. According to uncertain events, a multi-objective problem is hence performed. Here, to attain this, DE method on the basis of Pareto optimum procedure is proposed. The proposed methodology is employed for the IEEE 30-bus test system considering several cases and results are prepared to assess the optimum PMUs places.

Although non-renewable resources of energy and fossil fuels are coming to end in the next decades, but in recent years, consumption of fossil fuels in some modern or developing countries has been increased. Consumption of fossil fuels has increased the density of greenhouse gases in atmosphere, which encounters the world with irreversible changes. In order to decrease the unwanted environmental effects of fossil fuel consumption a worldwide trend has begun towards the use of renewable energy resources. In this paper, Optimization of structure and final hybrid system cost are investigated in order to meet the electricity demand of Meymand village, located in Iran. To find the optimum hybrid system, HOMER software is employed. The hybrid system consists of wind turbine, solar panels and diesel generator as main generating resources in addition to battery as energy storage system. The considered lifetime is assumed to be 25 years, and not only technical issues but also environmental and economic issues are investigated. According to the simulation results, the net percent cost (NPC) of the proposed hybrid system is equal to $37180, and levelized cost of energy (COE) is equal to 0.2 $/kWh. The technical, environmental and economic evaluations show that satisfaction of demand of Meymand village is more advantageous by hybrid system rather than the traditional one.
虽然不可再生的能源和化石燃料资源在未来几十年内即将结束,但近年来,化石燃料的消费在一些现代或发展中国家有所增加。化石燃料的消耗增加了大气中温室气体的密度,使世界面临着不可逆转的变化。为了减少化石燃料消耗对环境的不良影响,世界范围内开始出现使用可再生能源的趋势。为了满足伊朗Meymand村的电力需求,本文研究了混合系统的结构优化和最终成本。为了找到最优的混合动力系统,采用了HOMER软件。该混合动力系统由风力发电机、太阳能电池板和柴油发电机作为主要发电资源,外加电池作为储能系统。考虑的寿命假定为25年,不仅研究了技术问题,还研究了环境和经济问题。仿真结果表明,该混合动力系统的净百分比成本(NPC)为37180美元,平准化能源成本(COE)为0.2美元/千瓦时。技术、环境和经济评价表明,混合系统比传统系统更有利于满足梅曼德村的需求。
