Power droop control method of a microcomputer system for parallel operation of the distributed power communications network based on improved

This patent discloses a system for distributed micro power grid parallel operation of the improved communication network based droop control, droop control method designed to improve the conventional drawbacks, improvements in the parallel distributed power operating mode performance, improve the stability of the system for the integrated control system microgrid new energy distributed generation parallel mode of operation. The patent is based communications network, the micro controller of the grid system central controller and each inverter unit is integrally composed of a control system by calculating active and reactive power of a common load, each distributed correction power droop control scheme. With this scheme, it is possible to achieve better power equalizing effect, the smaller the frequency and amplitude of bus voltage deviation has a good prospect.
