Research On Intellegent Control Of Multi-energy-sources System

Growing shortage and growing pollution problems caused by conventional fossil fuels, make humanity have to actively look for new energy sources to maintain sustainable development. Solar and wind without pollution are widespread,can be seen as an important alternative future energy, attracting worldwide attention. Photovoltaic and wind power as conventional electric auxiliary powers areused more widely. Wind, solar and other new energies generation with the characteristics of intermittent volatility, etc., need reasonable scheduling when connected to the grid, to ensure safe and stable operation of the power grid, but with the massive new energy connected to the grid, reasonable scheduling becomemore difficult. When the output unstable wind power and photovoltaic power generation capacity is more than20%of the entire electricity grid, the grid is difficult to guarantee the safty and stability. So if the technical problems are not resolved, we can not let a lot of wind and photovoltaic power connect the grid.Therefore, this paper proposes a multi-energy intelligent scheduling system,capable of unified scheduling of photovoltaic, wind power and the stored energy.The system based on the relationship between current load power consumptionand renewable energy generating amount, reasonably control the access to eachmodule removal, making the entire system organic combination. If necessary, you can use the public power, to meet the changing needs of the load, but renewable resources are of higher priority. This paper first introduced the composedof multi-energy generation systems, including power generation principle and operating characteristics of each part, focusing on grid technology and grid strategy used in this paper. Then introduce multiple energy management content andscheduling based on fuzzy algorithm of this article. Finally, we established a variety of energy scheduling simulation models in MATLAB/simulink environment,and make some in-depth study of the system in the photovoltaic and grid-conn ecting module, and it turn out to achieve the desired goal.
