Research On Energy Coordination Optimization For Prosumer

As the contradiction between the shortage of traditional fossil energy and user's ever-growing electricity demand becomes more and more aggravating,the application of renewable energy has developed rapidly in the power industry,especially in the power generation field.Distributed generation has become more and more popular,turning the traditional power consumer into the power consumer and producer,and such users are defined as energy prosumers.The emergence of prosumer has changed the traditional power structure,and the power quality of the remaining power which is about to feed into power grid will affect the stable operation of the grid.Therefore,it is urgent to study the appropriate power load matching method inside the prosumer to weaken the adverse effects of distributed power generation and improve the economic efficiency of the prosumer system.This paper makes a specific study on the coordinated optimization of the energy in the prosumer.The main research contents are as follows:This paper analyzes the adverse effects caused by the power of distributed renewable energy generation fed into the power grid,as well as the research status at home and abroad of Energy router,the distributed power system framework and control strategy,optimizes the traditional system architecture,and proposes a Energy routerbased prosumer energy coordination optimization system.The core idea of this system is to realize the optimal matching of the internal power supply and loads of the prosumer by the Energy router,and the energy interaction between prosumers and the grid,and the local consumption of the power produced by renewable energy generation as much as possible to maintain the stable operation of the power grid.Under the condition that the system topology and operation modes are established,the mathematical model of the Energy router,distributed generation and loads in the system are established,and several optimization objectives,constraints and optimization algorithms that suitable for the system are designed.The Discrete Binary Particle Swarm Optimization Agorithm is applied to the Energy router-based prosumer energy coordination optimization system to realize the system function.An experimental platform for prosumer energy coordination optimization research is built,and the system is tested in an intraday statistical cycle.The test results show that the system can attain stability in long-term and transient operation;the algorithm is in order to ensure the critical users' comfort as much as possible,and the higher utilization rate of renewable energy.Meanwhile,it can maintain the economical and predictable operation of the system,and ensure the stable and reliable operation of the power grid.
