随着可再生能源渗透率的不断提高，配电系统潮流的方向和幅度可能会发生显着改变。这将使按需提供可靠电力成为一项重大挑战。本文提出了一种基于电池储能系统（BESS）的新型能源获取模型，用于配电公司（DISCO）的运营，调节价格或位置边际价格（LMP）机制，同时考虑 DISCO 控制区域内的能源供应选项。基于这个新模型，提出了一种新的电池运营策略，以更好地利用储能系统（ESS）并降低价格波动带来的运营风险。同时，通过成本效益分析方法获得BESS的最佳规模和选址决策，旨在使DISCO从能源交易、系统规划和运营成本节约中获得最大利润。所提出的能量获取模型和 ESS 控制策略在修改后的 IEEE 15 总线配电网络上进行了验证，并且还在两个不同市场中量化了风险缓解。令人鼓舞的结果表明，ESS 的容量需求可以降低，运营风险也可以降低。
Along with the increasing penetration of renewable energy, distribution system power flow may be significantly altered in terms of direction and magnitude. This will make delivering reliable power, on demand, a major challenge. In this paper, a novel battery energy storage system (BESS) based energy acquisition model is proposed for the operation of distribution companies (DISCOs) in regulating price or locational marginal price (LMP) mechanisms, while considering energy provision options within DISCO controlled areas. Based on this new model, a new battery operation strategy is proposed for better utilization of energy storage system (ESS) and mitigation operational risk from price volatility. Meanwhile, optimal sizing and siting decisions for BESS is obtained through a cost-benefit analysis method, which aims at maximizing the DISCO's profit from energy transactions, system planning and operation cost savings. The proposed energy acquisition model and ESS control strategy are verified on a modified IEEE 15-bus distribution network, and risk mitigation is also quantified in two different markets. The promising results show that the capacity requirement for ESS can be reduced and the operational risk can also be mitigated.
