摘要：

This paper presents a novel optimization model of dynamic voltage support planning. It considers the state transition course after great disturbance of large-scale receiving end networks (REN). The risk of contingency can be equivalent to the annual risk loss and it can be reduced by the appropriate dynamic voltage support. The annual risk loss consists of state separating risk costs and transferring risk costs. The objective function of dynamic voltage support planning is to maximize the yearly average profit of the state without and with additional dynamic voltage support for the power system. The model is able to describe all kinds of voltage instability scenarios caused by REN interior faults or interface failures properly. The optimal schemes of dynamic voltage support planning of Guangdong receiving end power grids in 2008 and 2010 are given as instance based upon the proposed model, which shows that the comprehensive allocation schemes are of great security and economical efficiency.
