含分布式电源配电网黑启动辅助服务定价策略

Pricing Strategy of Black Start Auxiliary Service in Distribution Network With Distributed Generation

针对分布式电源出力的波动性导致传统电网黑启动辅助服务定价方法不适用的问题,本文提出一种含分布式电源配电网黑启动辅助服务定价策略。以快速恢复更多重要负荷为目标优化各时段下进行黑启动时的负荷恢复范围以及恢复顺序,确定当天辅助服务提供方所能提供黑启动辅助服务的质量;根据黑启动辅助服务签订的负荷恢复时间、负荷等级以及负荷恢复量等协议内容,确定含分布式电源配电网黑启动辅助服务费的计算和黑启动辅助服务违约赔偿费的计算,并以辅助服务提供方总补偿费用期望最大为目标建立黑启动辅助服务签订时间优化模型,制定辅助服务提供方与各用户的最佳恢复时间签订方案。最后将总补偿费用分为能力补偿费与使用补偿费,通过评估各分布式电源本身的黑启动能力对能力补偿费进行分摊;以进行黑启动时各分布式电源的出力水平对使用补偿费进行分摊。以IEEE 69节点系统为算例,说明了所提策略的步骤与基本特征。

Aiming at the problem that the traditional black-start auxiliary service pricing method is not applicable due to the fluctuation of distributed power generation output,this paper proposes a black-start auxiliary service pricing strategy for distribution network with distributed power generation.Aiming at rapidly recovering more important loads,the load recovery range and recovery sequence during black start in each time period are optimized,and the quality of the black start auxiliary service that the power generator can provide on that day is determined;According to the load recovery time,load grade,load recovery amount and other agreement contents signed by the black-start auxiliary service,the calculation of the black-start auxiliary service and the calculation of the default compensation fee of the black-start auxiliary service in the distribution network containing the distributed power source are determined,the black-start auxiliary service signing time optimization model is established to obtain the maximum expected total compensation fee of the power generator,and the best recovery time signing scheme between the power generator and each user is formulated.Finally,the total compensation fee is divided into capacity fee and usage fee,and the capacity fee is shared by evaluating the black-start capability of each distributed power source.According to the actual black start of the distributed power supply output level to share the use fee.Taking IEEE 69-bus system as an example,the steps and basic features of this strategy are illustrated.
