Description

technical field [0001] The invention relates to the technical field of new energy storage, in particular to an integrated energy system based on a molten salt device. Background technique [0002] The traditional use of solar energy is relatively simple, usually for heating or power generation, but a lot of manpower, material and financial resources are invested in the construction process. Therefore, if only a single energy source is used for solar energy, for example, there is a problem of a large amount of energy wasted. [0003] The core of the multi-energy complementary integrated energy system (hereinafter referred to as the integrated energy system) is distributed energy and the regional energy supply around it, which is a form that integrates public cooling, heating, electricity, gas and even water services. On the one hand, the integrated energy system improves the utilization rate of renewable energy by realizing multi-energy collaborative optimization and compleme...
