Abstract

This paper proposes an energy management system (EMS) power dispatch algorithm for a set of various distributed energy resources such as distributed generators and energy storage system in hybrid configuration (HESS) connected to a 1-MW power grid system. The HESS is composed of a stationary centralized Vanadium Redox Battery and decentralized energy storage system represented by Li-ion electric vehicle (EV) charging parking lot at a commercial workplace. The proposed EMS incorporates vehicle-to-grid and grid-to-vehicle charging capabilities and detailed model of both incorporated battery technologies. Robustness, load levelling, peak shaving, ancillary service features and simulation results of the proposed EMS dispatch model were confirmed under the presence of different levels of power mismatch, the high intermittence of PV power output and the EV penetration. The simulation study is carried out with Matlab/Simulink considering the load profile curves of residential and commercial loads connected to the system with a 5 minutes dispatch interval.

电动汽车停车场+ VRB混合储能模式下光伏电站高间歇性调节的EMS策略

针对1兆瓦电网系统中分布式发电机和混合配置储能系统(HESS)等多种分布式能源，提出了一种能源管理系统(EMS)功率调度算法。HESS由固定的集中式钒氧化还原电池和以商业工作场所的锂离子电动汽车(EV)充电停车场为代表的分散式储能系统组成。拟议的EMS结合了车辆对电网和电网对车辆的充电能力，以及两种合并电池技术的详细模型。在不同程度的电力失配、光伏发电输出的高间歇性和电动汽车的渗透情况下，验证了所提出的EMS调度模型的鲁棒性、负荷均衡、调峰、辅助服务特性和仿真结果。采用Matlab/Simulink进行仿真研究，考虑5分钟调度间隔下接入系统的住宅和商业负荷的负荷分布曲线。
