Comprehensive self-consistent energy microgrid configuration method based on hydrogen energy storage and energy regulation and control method

Abstract

The invention relates to a comprehensive self-consistent energy microgrid configuration method based on hydrogen energy storage and an energy regulation and control method. An intelligent management and control system of a microgrid collects power-heat-cold energy consumption requirements of a microgrid load in real time, collects a real-time pressure intensity value of hydrogen in a hydrogen storage tank in the microgrid, and recognizes the relation between the microgrid and a power grid through an on-grid and off-grid judgment module; in an independent operation state that the micro-grid is merged into a power grid or the micro-grid leaves the power grid, the energy of the micro-grid is regulated and controlled by representing the energy storage capacity by using the real-time pressure value of hydrogen in the hydrogen storage tank, a result is judged based on the real-time pressure value of the hydrogen and a set hydrogen pressure boundary threshold value, whether wind power and photoelectricity in the micro-grid output power or not is combined, the micro-grid load cold and heat supply is jointly used as a constraint condition, and then a corresponding energy management and control strategy is started. On the basis of the wind and light prediction result and the typical daily load curve, instruction deviation caused by wind and light random and load fluctuation is adjusted and stabilized in real time according to the output of each unit in the day, and real-time balance of system energy and power is guaranteed.

Description

technical field [0001] The invention relates to the technical field of building energy supply, in particular to a hydrogen energy storage-based comprehensive self-consistent energy micro-grid configuration method and an energy regulation method. Background technique [0002] In recent years, energy storage technology has developed rapidly, and my country's energy storage industry has also ushered in a golden period of development for at least ten years. In order to coordinate the contradiction between the randomness and intermittent characteristics of distributed power and the reliable operation of the power grid, the micro-grid technology integrating distributed power, energy storage devices, loads, energy conversion devices and control and protection devices has been developed rapidly. However, due to the constraints of traffic, terrain and other reasons, civil energy storage power stations have brought serious constraints and impacts on the construction of micro-grids. Th...

However, due to the constraints of traffic, terrain and other reasons, the civil energy storage power station has brought serious constraints and influences to the construction of the micro-grid. There is an urgent need for a micro-grid that can adapt to special environments where energy supply is difficult such as islands and border posts. Power station construction plan
