Research On Distributed Frequency Adjustment And Optimization Scheduling Strategy Of Microgrid Based On MAS

In order to alleviate the lack of energy and environmental pollution,all countries in the world have made great efforts to develop and utilize new energy.Micro grid is an effective way of the new energy consumption.The wind power and the photo electricity are random and intermittent,which will destroy the active power balance of the micro grid,and will produce a serious frequency oscillation.Therefore,we need to be able to achieve fast and effective frequency adjustment to ensure the smooth and reliable operation of the system.Meanwhile,we must work out a reasonable allocation plan to further stimulate the economic potential of new energy.In addition,the new energy is scattered in the geographic space,and centralized scheduling will face many problems,such as the cost increase,the communication delay and so on.Therefore,it is of great theoretical and practical significance to study the distributed strategy for frequency adjustment and optimal scheduling in micro grid.In this paper,the multi agent system is used to study the distributed frequency adjustment and optimal scheduling strategy of microgrid.The output power of the new energy unit is greatly influenced by the surrounding environment.Based on the output characteristics of various energy sources,the output model of photovoltaic generation system and wind turbine generator is established,and the energy storage system is introduced to stabilize the output fluctuation of wind and light generating units.Based on the latest research trends,the frequency adjustment model of microgrid is established,and the benefit optimization index of microgrid is determined from two aspects,namely,the generation benefit of microgrid and the electricity efficiency of users.The output model of the unit,the model of frequency adjustment and the optimization of the scheduling target,and finally the optimal scheduling model of the microgrid is formed.Communication network based on MAS can realize distributed communication in microgrid,and introducing distributed optimization algorithm can effectively solve the optimal scheduling model of micro grid.Through the design of different simulation scenes,the effectiveness and practicability of the distributed scheduling strategy proposed in this paper is verified by many aspects.
