Problems solved by technology

[0003] However, PI control lacks the prediction of the future behavior of the controlled object, and cannot meet the requirements of small overshoot and short adjustment time at the same time. It is often difficult to balance speed and stability. Situations with complex characteristics and high control quality are often incapable

Abstract

The invention discloses a prediction control-based coordinated control system and method of an energy storage network. A control system is used for controlling a primary system of a same power distribution node in a power network, wherein the primary system comprises one or more energy storage units; the control system comprises a power prediction model unit and an optimal solving unit; the power prediction model unit is used for determining a power prediction model of the power distribution node according to control dynamic responses of the energy storage units; and the optimal solving unit is used for carrying out optimal solving according to a predicted value of the power prediction model and an optimized target value of power of the power distribution node to obtain optimal control values of the energy storage units. The method comprises the steps of building the power prediction model on the basis of the dynamic responses of the energy storage units of the power distribution node; and carrying out optimal solving according to the predicted value of the power prediction model and the optimized target value of the power of the power distribution node to obtain the optimal control values of the energy storage units. According to the prediction control-based coordinated control system and method of the energy storage network, the control effect can be predicted and the rapidity and the stability are taken into account.

Description

technical field [0001] The invention relates to the field of intelligent distribution networks, in particular to a predictive control-based coordinated control system and method for energy storage networks. Background technique [0002] The development and implementation of active distribution network technology has created conditions for the high penetration grid connection and coordinated control of distributed energy. It is the future development trend of smart distribution network to solve the current increasingly serious energy shortage and environmental pollution. question. The energy storage system with both power supply and storage capabilities is the key to the efficient and reliable active management and coordinated control of widely-connected distributed energy in the active distribution network. At present, the coordinated control methods of the active distribution network for the energy storage system are all based on PI control, so that the control quantity ca...
