Energy router based on energy gradient utilization and operation optimization method thereof

Abstract

The invention discloses an energy router based on energy gradient utilization and an operation optimization method thereof. The energy router comprises a gas turbine, a steam turbine, a waste heat boiler, an absorption refrigerating machine, a heat exchanger, a storage battery, a heat storage water tank and a photovoltaic battery. The system converts the fuel into electric energy according to thequality and the grade of the energy, and the waste heat is used for refrigeration, heat supply or power generation, so as to realize the gradient utilization of energy sources. According to the operation optimization strategy of the system, an optimized objective function is established by establishing a system model of the energy router, and optimizing scheduling solving is carried out after an optimization scheduling constraint condition is selected, and an optimized scheduling strategy is finally obtained, so that the system equipment can be correspondingly controlled according to the change of the user demands, and the optimization goal of maximizing the energy gradient utilization rate and minimizing the operation cost is achieved.

Description

technical field [0001] The invention belongs to the technical field of electrical engineering, and in particular relates to an energy router based on cascade utilization of energy and an operation optimization method thereof. Background technique [0002] Due to the depletion of global fossil energy and the deterioration of the global environment, the use of renewable energy has attracted more and more attention. With the rapid development of power electronics and computer information technology, renewable energy has developed rapidly. In order to better connect renewable energy to the grid, a new energy structure—the Energy Internet—has emerged. [0003] The Energy Internet is an intelligent network that integrates a large amount of renewable energy, especially distributed renewable energy, on the basis of the power grid to realize the distributed production and exchange of energy. The Energy Internet consists of energy routers, energy switches and energy interfaces. Amo...
