Abstract
This paper presents an investigation of voltage-and-frequency-(VF-) based battery energy storage system (BESS) controller used in micro grid for analyzing the optimum capability of plant. Microgrid is formed by using three hydropower plants feeding three-phase four-wire load. The proposed controller is used for load balancing, harmonic elimination, load leveling, and neutral current compensation. The proposed BESS controller permits the selection of an optimum voltage level of battery and allows independent current control of each phase. The main emphasis is given on maintaining constant voltage and frequency within the micro grid during transient conditions. Micro grid with power plant and its controller is modeled in MATLAB/Simulink using Power System Blockset (PSB) toolboxes.
研究了基于电压频率的电池储能系统(BESS)控制器在微电网中的应用，以分析电站的最优发电能力。微电网由3座水电站馈电三相四线制负荷组成。该控制器用于负载平衡、谐波消除、负载均衡和中性点电流补偿。所提出的BESS控制器允许选择电池的最佳电压水平，并允许每个相位的独立电流控制。主要的重点是在瞬态状态下保持微电网内的恒定电压和频率。利用电力系统块集(power System Blockset, PSB)工具箱，在MATLAB/Simulink中对带电厂的微电网及其控制器进行建模。
