配电网中的电能存储系统集成

Electric Energy Storage Systems integration in Distribution Grids

Alessandro Di Giorgio, Francesco Liberati, Andrea Lanna

摘要:

本文提出了一种实时控制策略,用于动态平衡电力需求和供应在当地一级,在一个场景中,其特征在于由一个高压/中压变电站与可再生能源的光伏发电机和电能存储系统的形式存在。变电站连接到电网,并由扮演大容量电力系统角色的等效传统发电厂供电。提出了一种基于模型预测控制的方法,通过该方法,传统发电厂和存储器的有功功率设定值随着时间的推移不断更新,这取决于发电成本、存储器的荷电状态、可预见的需求和可再生能源的产量。所提出的方法是在仿真的基础上进行验证,显示其有效性在管理网络需求和光伏发电在测试和真实条件下的波动。

英文摘要:

This paper presents a real time control strategy for dynamically balancing electric demand and supply at local level, in a scenario characterized by a HV/MV substation with the presence of renewable energy sources in the form of photovoltaic generators and an electric energy storage system. The substation is connected to the grid and is powered by an equivalent traditional power plant playing the role of the bulk power system. A Model Predictive Control based approach is proposed, by which the active power setpoints for the traditional power plant and the storage are continually updated over the time, depending on generation costs, storage's state of charge, foreseen demand and production from renewables. The proposed approach is validated on a simulation basis, showing its effectiveness in managing fluctuations of network demand and photovoltaic generation in test and real conditions.
