摘要

为在电力市场和调度运用中发挥用户侧分布式储能的价值,充分利用电价的优化调节能力,提出考虑负荷需求响应的多目标双层动态电价模型。其中,上层以区域配网代理运营商运营成本和平均负荷波动率最小为目标,下层考虑储能商负荷需求响应,以各储能商运营成本最小为目标。此外,采用改进优劣解距离法对模型求得的Pareto最优解集进行多属性决策,以避免传统优劣解距离法中人为赋权的主观性。最后,决策出最优的内部电价、充放电计划和负荷安排。算例表明,该策略可以降低储能商的运行成本,提高区域配网运营商的收益与区域供电可靠性,同时有利于平滑负荷曲线。

Abstract

To utilize the value of distributed energy storage on the power market and in dispatching applications, this paper proposes a multi-objective double-layer dynamic electricity pricing model considering load demand response for user-side distributed energy storage. The upper layer considers the objectives of minimizing the operational cost and average load fluctuation rate of regional distribution network agents, while the lower layer considers the load demand response of energy storage merchants, with the objective of minimizing the operational cost of each user-side energy storage aggregator. In addition, an improved inferiority distance method is used to perform multi-attribute decision-making on the Pareto optimal solution set obtained from the model, in order to avoid the subjectivity of the traditional inferiority distance method. Finally, the optimal internal electricity price and charging and discharging plan are determined. Case studies show that this strategy can reduce the operating cost of energy storage aggregators, improve the revenue and reliability of regional distribution network operators, and also be benefit to smooth load curves.
