Abstract

The invention discloses a system and a method for controlling a distributed power and energy storage system-containing power distribution network. The system and the method are used for controlling the optimized operation of the distributed power and the energy storage system, which are accessed in a synchronization way, in a power distribution network. The system and the method are used for computing the difference between a measured value of the exchange power of the power distribution network and an external power network and the optimum value or a planed target value obtained by means of optimal computation and defining into the running error of the power distribution network, and are applicable to the closed-loop control on the energy storage system and the distributed power, so that the power distribution network can be kept to be consistent with the actual value of the external power exchange power and the optimum value or the planed target value computed in an optimizing way.

Description

technical field [0001] The invention relates to a control system of a distribution network, in particular to a constant exchange power control system of a distribution network including a distributed power source and an energy storage system. The invention also relates to a constant exchange power control method for a distribution network including a distributed power supply and an energy storage system by using the system. Background technique [0002] After accessing the distributed generation (DG) and energy storage system, the distribution network has a certain ability to actively adjust and optimize the load. However, renewable energy has the characteristics of intermittent or fluctuating, which limits the grid-connected operation of DG, and it is necessary to optimize the control and scheduling of DG. The active management of distribution network and grid-connected DG and energy storage system can improve the number of DG grid-connected and operational efficiency. Th...
