Research On Microgrid Dispatching Method Based On Particle Swarm Optimization

With the problem of energy and environmental pollution getting more and more serious,the development of clean and renewable energy resources has been the concern of all countries in the world.Clean energy with huge reserves Wind power and solar power has seen rapid growth.Microgrids have become an important form of power generation that accepts new energy,both for energy exchange with large power grids and for autonomous operation.As wind power and solar power are greatly affected by the environment,microgrids need appropriate energy management strategies to ensure the microgrid can operate stably and efficiently.Based on the analysis of the energy control strategy of the microgrid,this paper establishes the microgrid energy dispatching model,which uses the particle swarm optimization algorithm to solve the microgrid energy dispatching model.Firstly,the paper briefly introduces the concept of microgrid and its research background and status quo.Through references and the development of energy environment today,the superiority of microgrid and the development prospect of microgrid are put forward.According to the analysis of traditional microgrid energy management strategy,the existing problems in energy management of microgrid are proposed,and the main tasks and management structure models of microgrid energy dispatching proposed in this paper are proposed.In this paper,a mathematic model of microgrid energy management of photovoltaic,wind power,micro-gas turbines,and energy storage equipment is established and analyzed in detail according to the power generation principle and dispatching characteristics of each distributed generation unit in the microgrid,using Matlab/ Simulink simulation module to build photovoltaic power generation and wind power generation simulation model respectively..Taking into account the power conservation,fuel cost,and interactive cost of large power grids in each distributed unit in the microgrid,the author analyzes the operation characteristics of various distributed power units in the microgrid and analyzes the output of each distributed power unit randomly Energy Regulated Microgrid Energy Dispatching Model.According to the predictive interval value of the output of the fan and PV,and then considering the time-exchange electricity price,considering the energy exchange between the microgrid and the large power grid,a mathematic model of particle swarm optimization based on particle swarm optimization Improve the premature convergence of particle swarm.The result of the example verifies the good robustness of the proposed model and method and shows the effectiveness of the solution to the uncertainty optimization problem.
