Abstract

With the wide application of renewable energy power generation technology, the distribution network presents the characteristics of multi-source and complex structure. There are potential risks in the stability of power system, and the problem of power quality is becoming more and more serious. This paper studies and proposes a power optimization cooperative control strategy for flexible fast interconnection device with energy storage, which combines the flexible interconnection technology with the energy storage device. The primary technology is to regulate the active and reactive power of the converter. By comparing the actual power value of the converter with the reference value, the proportional integral (PI) controller is used for correction, and the current components of d and q axes are obtained and input to the converter as the reference value of the current inner loop. The control strategy in this paper can realize power mutual aid between feeders, and at the same time, the energy storage device can provide or absorb a certain amount of power for feeders, so that the power grid can realize stable operation in a certain range.
