Background: The Demand Side Management (DSM) technology is playing an increasingly
important role in the power system, in order to promote the real-time supply and demand balance
of the power grid and improve the economy and safety of the power grid.
Objective: To realize the flexible and continuous reactive power control of demand side load, a reactive
power control strategy for the demand side back-to-back converter (DS-B2BC) is proposed.
Methods: First, DS-B2BC is proposed. Then, the reactive power control model of DS-B2BC and its
control loop are designed, and the reactive power control model, based on the Virtual Synchronous
Motor (VSM), is established.
Results: The simulation results verify that the reactive power control strategy proposed in this paper
is effective, which can control the demand side load reactive power flexibly and continuously.
Conclusion: Moreover, the strategy can counteract the disturbance from the power grid simultaneously.
