Abstract

The invention discloses a multi-microgrid flexibility improvement method based on mobile energy storage, and belongs to the technical field of microgrids. Calculating confidence intervals of fan and photovoltaic output; establishing a risk assessment model considering wind and light uncertainty; establishing a mobile energy storage transportation model considering truck transportation time and blocking delay; establishing a multi-microgrid optimization operation model based on mobile energy storage; and solving the multi-microgrid optimization operation model to obtain a configuration scheme of a mobile energy storage position and charging and discharging power and a dispatching scheme of a diesel generator, a fan and a photovoltaic device. According to the method, the problem of insufficient flexibility of the system in an environment with uncertain wind and light resources can be effectively solved through a coordinated operation strategy, and a configuration scheme of a mobile energy storage position and charging and discharging power and a scheduling scheme of a diesel generator, a fan and photovoltaic power are determined.

Description

technical field [0001] A method for improving the flexibility of multiple microgrids based on mobile energy storage belongs to the technical field of microgrids. Background technique [0002] With the accelerated development of the global economy, energy shortage and environmental pollution have become serious problems, which also promotes the research and development of renewable energy power generation. Wind and wind resources occupy a very important position in many renewable energy resources. Integrating the distribution network with high penetration of wind and solar resources will bring many benefits such as reducing power loss, reducing environmental pollution, and increasing the penetration rate of renewable energy. As a form of effective utilization of renewable energy, microgrid has developed rapidly. The advantages of microgrids include improving the reliability, sustainability, and quality of power supply and reducing operating costs and losses of transmission a...
