Problems solved by technology

On the one hand, making full use of green new energy such as water energy, wind energy, and solar energy is an effective solution. However, it is technically difficult to connect the power of new energy to conventional power systems with high conversion efficiency and large-scale non-destructive. To some extent, it limits the practical application of green new energy

Abstract

The invention discloses a collaborative optimization method and device for an electric vehicle group and a building group, an apparatus and a medium. The system is composed of N electric vehicles and M buildings, wherein each building is equipped with a photovoltaic power generation system, a constant temperature regulator system and an electric vehicle charging pile. According to the method, a scene tree method is adopted to solve the randomness problem, an expected scene of energy interaction brought by photovoltaic power generation, building loads and electric vehicle movement is established according to the solar radiation intensity, the set temperature of a constant temperature regulator and the energy interaction brought by the electric vehicle movement, and aiming at minimizing the average operation cost under all the scenes, the mixed integer linear programming is carried out on the system to research an operation strategy of the system. In the optimization problem, the operation strategies of photovoltaic power generation and building loads in all situations are kept the same, while the operation strategies of charging and discharging of the electric vehicles in different situations are variable, so that the purpose of absorbing new energy is achieved.

Description

technical field [0001] The invention belongs to the technical field of multi-energy systems, and in particular relates to a collaborative optimization method, device, equipment and medium for electric vehicle groups and building groups based on new energy. Background technique [0002] Economic development has sharply increased the demand for energy, leading to the depletion of traditional chemical energy sources such as coal, natural gas, and petroleum. At the same time, the extreme exploitation and excessive use of fossil energy have caused harsh environmental problems such as acid rain and smog, which seriously threaten human health and healthy social development. . Therefore, the traditional energy consumption model dominated by fossil energy can no longer fully meet the demand. How to find a new energy consumption model and solve the conflicting problems of energy consumption and environmental protection is the key to the sustainable development of society. On the one...
