Power Coordination Control Of Forest Microgrid Based On Nonlinear Consensus Algorithm

With the advent of the "Internet+" era,traditional forestry is gradually moving toward "smart forestry." This has increased the demand for electricity in the forest area.However,due to the remote location of the forest region,it is difficult to set up the power supply line and the power quality cannot meet the requirements with the traditional large power grid.Independent micro grid provides a new idea for solving the problem of power supply in the forest region.For the independent micro grid applied in the forest area,most of its internal distributed power sources are renewable energy power sources and energy storage units based on the interface of power electronic devices.To solve this problem,this paper proposes a power coordination control strategy for forest microgrid based on nonlinear consistency algorithm.The main work and innovative achievements are as follows:(1)Combined with JiuFeng forest park to establish the specific needs of micro power grid,is presented for the woods OuDeWei grid topology structure,and set up detailed micro grid electromagnetic transient model,including photovoltaic cells,battery and load,etc.,analyzes the characteristics of the micro grid operation under different light;On this basis,from the perspective of the whole power control,the equivalent model of the basic control unit(optical storage distributed power supply)in the microgrid is derived and given.(2)By considering the forest region of solar photovoltaic power and energy storage limit of maximum output power,and the diversity of the forest area load,Put forward based on nonlinear consistency algorithm in dc micro grid power coordination strategy,in order to realize in light intermittent random fluctuations and load for the forest under the scenario of micro grid can stable operation.(3)Based on MATLAB/Simulink built respectively JiuFeng forest park dc micro grid and IEEE standard 37 simulation model of dc micro grid nodes respectively to load fluctuations,distributed optical power output power storage scene simulation analyses,such as this paper is verified the effectiveness of the proposed power coordination strategy.
