Probabilistic Load Flow Calculation of Power Systems Considering Wind Power Dispatching Strategies
摘要
Abstract
The paper proposes a method to calculate multi-point linearization probabilistic power flow of power systems considering the dispatching strategies of wind power. The proposed approach is based on the theory of Cumulant and Gram-charlier series, and takes into account the uncertainty of wind power, conventional power generation and load. To ensure accuracy, multi-point linearization technology is applied. In addition, the dispatching strategies of wind power are also considered in power flow calculation, as it did in power system economic power dispatching. Compared with simulation-based methods, the proposed approach can not only effectively improve the calculation accuracy compared with Cumulant and Gram-charlier series methods, but also can overcome the disadvantage of conventional probabilistic power flow calculation, i.e., the unbalanced power fluctuations are entirely absorbed by the slack bus. Therefore, the calculation results obtained through the proposed method is more consistent to reality.关键词
