Optimal configuration of wind and photovoltaic capacity based on power variation active response ability of cascade hydropower and energy intensive load

In order to effectively solve the problem of high proportion of wind and photovoltaic power permeation, an optimal configuration method of wind and photovoltaic capacity based on power variation active response ability of cascade hydropower and energy intensive load is proposed. The coordination framework of energy intensive load and cascade hydropower in suppressing the fluctuation of wind and photovoltaic power output is designed. By describing the power regulation characteristics of cascade hydropower at different time based on water head change and the power regulation characteristics of energy intensive load based on the production process, an optimal configuration model of wind and photovoltaic capacity considering system regulation ability constraints is built, which takes the minimum investment and construction cost of wind and photovoltaic power stations, the operation cost of hydropower and thermal power stations, the dispatching cost of energy intensive load and punishment cost of wind and photovoltaic power abandonment as its object to determine the wind and photovoltaic installed capacity. The simulative results of a region in Hunan show that the proposed method can better smooth net load power fluctuation, increase the wind and photovoltaic integration capacity.
