Study Of The Planning Scheme Of The Huanglian Photovoltaic Plant

Development and utilization of the renewable energy generation has become the focus of many countries with the depletion of the fossil energy and the environment pollution.The renewable energy generation,including the wind power generation and the photovoltaic generation,developed rapidly in recent years.With the features of variation,randomness,uncontrollability and electronization,photovoltaic generation is challenging the safety operation of the power grid.The rational planning scheme of the photovoltaic plant can reduce the harmful influence of the photovoltaic power on the power grid significantly.This paper studied the planning scheme of the Huanglian photovoltaic plant.The planning scheme of the photovoltaic plant is proposed.Calculation results verify the rightness of the proposed scheme.The research background and significant of the planning of photovoltaic plant is introduced in this paper.The research status of the topic is summarized.Then,the basic principle of the photovoltaic system is given.The mathematical model and planning model of the photovoltaic plant is described.Then,the planning scheme of the Huanglian photovoltaic plant is proposed.The mathematical model of the photovoltaic plant is built while considering the geographical position of photovoltaic plant and the structure of grid.The planning scheme of the photovoltaic plant is obtained by solving the mathematical model.Finally,calculation to the planning schemes of the photovoltaic plant is performed.Thus the optimal planning scheme is obtained.Some indexes,such as the short circuit current,consumption and so on,are calculation.The calculation results can evaluate the economy and technology indexes.Thus,the optimal planning scheme of the photovoltaic plant is obtained.
