The PV Capacity Analysis In PV-Hydro Combined Operation System

In recent years,PV as a green and new power generation is most popular power by people,but PV has the key point disadvantage compared to conventional power generation mode,it is the instability of power generation.Because of this shortcoming,PV can not to be used in a large number.To eliminate fluctuations in PV generation is an important direction now.The PV-Hydro operation system as a new generation model not only can eliminate the fluctuations of PV,but also can make more efficient use of solar energy.First of all,this article introduced the part of a operation system,include PV and hydropower.And then introduce the PV model,hydro model and its output characteristics.On this basis,PV – Hydro operation system make sure that system’s output should satisfy the grid’s load requirements,and by optimizing the configuration of the PV with respect to hydropower capacity to achieve integrated revenue maximization.In this paper,particle swarm algorithm,photovoltaic,hydro power generation earnings maximum objective function,photovoltaic,hydro maximum output and minimum output as the constraints.In a day’s data is calculated on the basis of photovoltaic power generation capacity.Were analyzed before and after optimization and optimization of photovoltaic capacity in the day,the month and the year combined output of photovoltaic systems,hydropower.Before comparing capacity optimization,optimization of comprehensive income after the joint system to prove after the capacity optimization through,although because of improved photovoltaic capacity and improve the investment,but also increase the annual income of the joint system,and funds can be invested in short time to recover the cost.
