With the rapid development of the society and economy and the accelerated construction of new power systems,flexible interconnection has gradually become an important technical means for upgrading the structure and enhancing the flexible regulation ability of distribution network.A power coordinated control strategy for engineering applications was proposed to address the power control requirements of multi-terminal flexible interconnection systems,including heavy-load limiting control for the rational power distribution when some feeder lines were heavy-loaded,and power balance control for power flow optimization distribution when all feeders were heavy-loaded.A flexible interconnection coordinated control device was developed based on the proposed strategy and applied to practical engineering.The case analysis based on the real load data and the measured data of the project verify that the proposed strategy can deal with different flexible interconnection scenarios with different load/power characteristics,effectively solve the problems of unbalanced feeder load and reverse PV power flow in the distribution network,and improve the power supply efficiency and security.
