摘要

针对多个虚拟电厂间协调互动存在的能量耦合问题,提出共享储能服务质量定量评估函数,建立计及服务质量评估的多虚拟电厂能量共享双层优化模型。上层兼顾共享储能的经济效益与服务质量,优化其容量配置;下层考虑虚拟电厂运行经济性,优化其内部机组出力及交易电量。针对新能源出力的不确定性,建立计及机会约束的优化模型。模型采用KKT条件及大M法将双层模型转化为等效单层模型进行求解。仿真验证所提模型的合理性,算例分析共享储能服务质量及置信度水平对于多虚拟电厂能量共享及储能配置的影响。结果表明,考虑共享储能服务质量可有效提升虚拟电厂参与电能共享的积极性,实现资源的合理利用。

Abstract

Aiming at energy coupling problem existing in the coordination and interaction among multiple virtual power plants （MVPP）, a quantitative evaluation function of service quality for shared energy storage （SES） is established. Combined with the evaluation function, a bi-level optimization scheduling strategy of energy sharing among MVPP is proposed. In the upper level, taking into account both the target of economic benefits and service quality of SES, the capacity allocation is optimized. In the lower level, the units output within MVPP and transaction power among them are optimized to minimize the operation cost. To address the uncertainty of RE, based on chance constraint, an optimization model is constructed, where the KKT condition and the Big-M method are used to transform bi-level model into an equivalent single-level model. Simulation verifies the rationality of the proposed model and cases analysis are employed to demonstrate the impact of SES service quality and confidence level on energy sharing and energy storage configuration of MVPP. In addition, results show that with the consideration of service quality for SES, the enthusiasm of MVPP to participate in power sharing is enhanced effectively, realizing the rational utilization of resources.
