基于负荷功率特征分区的用户侧储能经济运行优化

为充分发挥储能在需量管理、分时电价管理、电能质量优化等方面的多元价值，提升用户侧储能项目运营经济性，采用极坐标相量法对用户侧负荷和储能功率特征分布进行分析，提出了基于负荷功率特征分区的用户侧储能经济运行优化策略，可有效减少用户基本电费、电度电费和功率因数调整电费，且参数选取简单，便于工程应用推广。

Economic Operation Optimization of User-Side Energy Storage System Based on Complex Power Characteristic Zone of Load

In order to improve the operational economics of user-side energy storage (ES) projects and take full advantages of ES in demand management, time-of-use electricity price management and power quality optimization, in the paper, the complex power characteristic distribution of load and ES are analyzed with the phasor method in polar coordinate. Then an economic operation optimization strategy for user-side ES is proposed based on the load power characteristic zone, which can effectively reduce the user's capacity tariff, electric tariff and power-factor regulating tariff. Additionally, because of its simple parameter setting, it is convenient for the promotion of engineering applications.
