doi:10.11930/j.issn.1004-9649.202004196

Abstract

Abstract: 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.

Key words: energy storage system, operation optimization, power characteristic distribution, power factor, demand management
