考虑广泛负荷聚合商无功调节优先权的调度决策模型

针对柔性负荷、分布式储能和分布式电源等负荷聚合商在参与电力市场调度中存在的问题,整合各类分布式资源构成广泛负荷聚合商,建立考虑无功调节优先权的广泛负荷聚合商参与电力市场调度的决策模型。首先,考虑不同分布式资源在参与电网调度时的无功可调节水平、无功调节可信度、调节经济性与有功支撑水平方面的特性,基于熵权法建立考虑无功优先权的调度评估模型;然后,以广泛负荷聚合商参与电力市场调度的收益最大为目标建立调度决策模型及其求解方法;最后,通过算例仿真表明该文提出的调度决策模型的有效性和经济性。

DISPATCHING DECISION MODEL CONSIDERING REACTIVE POWER ADJUSTMENT PRIORITY OF EXTENSIVE LOAD AGGREGATORS

In view of the problems that load aggregators such as flexible loads, distributed energy storage and distributed power sources have in participating in power market dispatching, this paper integrates various distributed resources to form a wide range of load aggregators, and establishes a decision model for the participation of extensive load aggregators in power market dispatch considering reactive power priority. Firstly, considering the characteristics of the reactive power adjustable level, the reliability of reactive power regulation, the regulation economy and the active power support level of different distributed resources when participating in grid dispatching, a dispatch priority evaluation model based on the entropy weight method was established in this paper. Then, this paper establishes a decision model and its solution with the goal of maximizing the benefits of a wide range of load aggregators participating in power market. Finally, a simulation example shows the effectiveness and economy of the decision model proposed in this paper.
