Water-light-hydrogen complementary microgrid power generation system and method

Abstract

The invention relates to the technical field of hydroelectric generation, in particular to a water-light-hydrogen complementary microgrid power generation system and method. The system comprises a water-light complementary system composed of a hydroelectric generation system and a photovoltaic power generation system, a hydrogen energy storage system, an AC / DC device, a DC / AC device and a hydrogenfuel cell, wherein the power supply output end of the water-light complementary system is connected with the power supply input end of the hydrogen energy storage system through the AC / DC device, thehydrogen outlet of the hydrogen energy storage system is connected with the hydrogen inlet of the hydrogen fuel cell through a pipe, and the power supply output end of the hydrogen fuel cell suppliespower to a load through the DC / AC device. Excessive electric energy generated by the water-light complementary system is subjected to water electrolysis hydrogen production, electric energy is provided when power supply is insufficient, the renewable resource utilization rate is effectively increased, the operation and maintenance cost is reduced, and the power supply is more stable.

Description

technical field [0001] The invention relates to the technical field of hydroelectric power generation, in particular to a water-solar-hydrogen complementary micro-grid power generation system and method. Background technique [0002] my country is rich in water resources, and hydropower construction has achieved world-renowned achievements, and its economic and social benefits are remarkable, but there are also some problems that cannot be ignored. For example, the power load of some hydropower transmission areas is not coordinated with the natural runoff. In remote areas in the west, the power generation capacity of hydropower stations is greatly affected by seasons and natural conditions, and once the hydropower stations are put into operation, it will be difficult to expand the installed capacity again. Most of the western part of my country is a high-altitude area with abundant solar energy resources, which is suitable for the development of photovoltaic power generation...

Problems solved by technology

Although the existing water-solar hybrid system has better and more stable power supply capacity compared with separate hydropower and photovoltaic power generation, due to the peaks and troughs of the load, the hydro-solar hybrid system still has insufficient power supply at peak loads, and the load The Problem of Overcapacity in Low Times
