Abstract

The invention discloses a wind-solar-storage complementary distributed energy power generation system and a control method thereof. The system comprises a wind power generation device which is used for generating power through wind energy and outputting alternating current, a luminous energy power generation device which is used for generating power by utilizing luminous energy and outputting direct current, and an energy storage device which is used for storing electric energy to absorb redundant electricity when the voltage on a direct-current bus is higher than rated voltage, and is used for releasing the electric energy to maintain the stability of the voltage on the direct-current bus when the voltage on the direct-current bus is lower than the rated voltage, wherein the energy storage device adopts a hybrid energy storage mode of a storage battery and a fuel cell. While complementarity of wind energy and light energy in time and space is fully utilized, the energy storage device is added to solve randomness and intermittency of wind energy and light energy output power, and a reliable and safe control strategy can be provided for new energy grid connection.

Description

technical field [0001] The invention belongs to the technical field of new energy complementary power generation control, and in particular relates to a distributed energy power generation system and a control method thereof. Background technique [0002] There is a big difference between renewable energy and traditional generator sets, mainly because the power output of renewable energy is an uncertain quantity; among them, wind energy and solar energy have the characteristics of randomness and intermittency, and if they are directly connected to the grid, the load on the grid will vary. Balance, and even cause the power system to be paralyzed, unable to continue to provide market power supply. With the growing development of renewable energy, the impact of renewable energy grid integration on the grid is also increasing. The volatility and unpredictability of renewable energy make it very difficult to grid-connect. At present, besides economy, the bottleneck restricting t...
