A new dispatch and control method for active power of wind farm clusters based on fusion information is proposed, which minimizes the total power curtailment and total power shortage, on the base of grasping and using the correlation among wind farms, and also maximum output for a single wind farm and total wind power of the cluster fulfilling the requirements of the power system dispatch instruction...
In order to solve the problem of voltage stability existed in wind farms interconnected to power system, a computing method taking the statistical law of wind output power into account is proposed to determine the reactive power compensation capacity that is interconnected to power system. Based on the statistical law of wind power and considering the characteristics of reactive power and active power...
Wind power's volatility and intermittence have a profound impact on power system's security and economic operation. However, high-precision power prediction is the important prerequisite to reduce the influence of wind power on the power system. This paper illustrates a wind power prediction model based on time-series and back propagation artificial neural network (BP-ANN), considering wind speed,...
The wind farm with Crowbar protection will change from reactive power source to reactive power load when low voltage ride-through occurs, then the burden of the fault power system is aggravated. To solve this problem, a new strategy of real time reactive power voltage coordinated control is proposed, and a real time coordinate control system (RTCCS) is also built. The strategy realizes real time coordinated...
