Constant power control method of switching power distribution network having distributed power and energy storage systems

Control system and method for containing energy storage and distributed power distribution network systems, distributed power supply grid and for network access with optimal operation control energy storage system. The difference between the optimum value and the measured value or the planned target optimization calculation by calculating a power distribution network according to the present invention with the outer switching power grid obtained, defined as operating error distribution grid, and applied to the energy storage system, distributed power closed-loop control, the optimal value or actual value and the planned optimization of the calculated power distribution network with foreign exchange target consistent.
