Direct electricity-heat conversion type efficient energy storage and release system

Abstract

The invention discloses a direct electricity-to-heat type efficient energy storage and release system which comprises an IGBT power module, the IGBT power module is connected with an electricity-to-heat storage module through a cable, the electricity-to-heat storage module is connected with a fluidized heat exchange module through a pipeline, and the fluidized heat exchange module is connected with a solid heat storage material intermediate tank through a pipeline. The solid heat storage material intermediate tank is further connected with the electricity-to-heat heat storage module through a pipeline, and the fluidization heat exchange module is connected with a power generation or heating module through a hot air circulation module and forms a circulation loop with the power generation or heating module. According to the direct electricity-to-heat type efficient energy storage and release system, the problems that in the prior art, electricity-to-heat energy storage cannot be directly connected with a middle-high voltage power grid, and the energy storage and release rate is low are solved.

Description

technical field [0001] The invention belongs to the technical field of energy storage, and relates to a direct electric heat transfer type high-efficiency energy storage and release system. Background technique [0002] In the context of the "dual carbon" goal, build a clean, low-carbon, safe and efficient energy system, improve the level of clean energy utilization and the operating efficiency of the power system, promote the integration of source, grid, load and storage and multi-energy complementarity, and improve the development and consumption of renewable energy. The level of sodium and the proportion of non-fossil energy consumption are of great significance. In order to achieve the above goals, it is particularly important to establish a high-voltage and high-power electrothermal conversion and reuse system. Based on sensible heat energy storage, this patent builds a direct electric heat transfer high-efficiency energy storage and release system that meets the above...
