利用电池储能系统进行区域配电网的峰值负荷缓解

Regional distribution networks (RDNs) frequently encounter challenges related to peak load demands, such as increased system operational costs, grid instability, transmission and distribution line losses, and decreased system efficiency. Thus, this study specifically examines the practice of peak shaving for RDN by employing a battery energy storage system (BESS) in order to decrease overall operational expenses and improve system performance. A centralized peak shaving technique is developed using an economic size of BESS to provide optimal peak shaving performance. Real load data is utilized in this work to eliminate the forecasting errors which is collected from a real RDN located in Australia. The developed technique is applied to real RDN furnished with real data to undertake a variety of simulation tests aimed at assessing peak shaving performance. A comparison study is used to demonstrate the success of the improved peak shaving operation by comparing it with previous strategies. The result reveals that the developed method with an economic size of BESS can generate substantial electricity savings and economic benefits, with a net revenue over investment 2.2 times higher.
