Cold, heat and electricity triple generation new energy storage and supply and peak shaving system

Abstract

The invention discloses a cold, heat and electricity triple generation new energy storage and supply and peak shaving system. The system comprises a new energy power generation subsystem, an industrial electromagnetic heating device, a fused salt storage tank subsystem, a fused salt heat supply subsystem and a public power distribution network; the new energy power generation subsystem provides electric energy to the industrial electromagnetic heating device, a system load and the public power distribution network; the industrial electromagnetic heating device converts most electric energy generated by photovoltaic and wind power new energy power generation subsystems to heat energy for storage by fused salt; the fused salt heat supply system is used for external heat supply; part of the electric energy can be supplied to the system; and redundant electric energy can be supplied to a public power grid. The heat energy provided to the external can provide steam for warming heat sources,domestic hot water and centralized refrigeration to such users as residents and office places, and can provide industrial steam and steam for deep power generation peak shaving, so that the problem of weak new energy power generation peak shaving performance is solved, and the problems of difficult consumption and wind and light abandoning in the new energy field are solved.

Description

technical field [0001] The invention belongs to the fields of new energy storage and energy supply, peak regulation and consumption, and environmental protection, and specifically relates to a new energy storage energy supply and peak regulation system for triple supply of cold, heat and electricity. Background technique [0002] For a long time, my country's energy consumption is still dominated by coal, and its damage to the ecological environment is well known. Among them, coal-fired power generation and coal-fired heat supply are the main damage to the environment. [0003] Coal-fired heating problem: In winter, urban residents need to rely on coal-fired cogeneration units to provide central heating; in terms of rural heating, due to the scattered nature of rural villages and investment cost constraints, it is not possible to lay central heating pipelines. Therefore, most of the vast rural areas in northern China still use self-made water circulation coal-fired heating f...
