Load Recovery during Power System Blackstart

LIU Ying-shang1,WU Wen-chuan2,FENG Yong-qing3,ZHANG Bo-ming2 (1.Department of Production &Technology,China Southern Power Grid,Guangzhou 510623,Guangdong Province,China; 2.State Key Lab of Control and Simulation of Power Systems and Generation Equipments(Department of Electrical Engineering, Tsinghua University),Haidian District,Beijing 100084,China;3.Power Dispatching and Communication Center of China Southern Power Grid,Guangzhou 510623,Guangdong Province,China)  
The load recovery and the connection of subsystems with power grid during the blackstart of subsystem are researched. Firstly, by means of integrating the rectangular coordinates based weighted optimal multiplier Newton-Raphson method with sensitivity analysis and adopting continuous linear programming method, both mathematical model and algorithm for restoration control to solve the infeasibility of N?1 power flows and out-of-limit states, which appear at load recovery stage, are established; secondly, the models and algorithms to simulate the frequency variation of subsystems at load recovery stage are established; finally, for the problem of connecting subsystems with power grid, a continuous linear programming based optimal generation re-dispatching method is also developed to control the voltage difference between different islands, thus the optimal voltage difference control at the position where the connection is taken place is effectively implemented. The effectiveness of the proposed model and algorithm is verified by simulation results of standard testing system and actual power grid.
