Setting Method of Reactive Power Interval for Substation Gateway Considering Stochastic Volatility of Wind Farm
摘要
Abstract
Since the control range of reactive power of substation gateway ( RPSG) in traditional nine ‐zone automatic voltage control ( AVC) strategy cannot adapt to output fluctuation of wind farm in a distribution network , the active loss characteristic of distribution network with distributed wind power integration is analyzed . An optimal interval matrix is defined , the physical meaning and calculation method of matrix elements are explained . To obtain the corresponding element value , the intersection of optimal intervals of RPSG under different load levels is set . The intervals are obtained and improved according to the correlation characteristic between the active loss and RPSG and the voltage limits when the wind power output changes . A block interval method is proposed to obtain the control interval which can adapt to the wind farm operation condition . The simulation shows that the setting methods are simple and practical in engineering , which realize the multi‐objective of volt/var control such as saving energy , avoiding frequent regulation and improving voltage quality .关键词
