【Abstract】 In the security constrained economic operation of power system, the problem of reactive power flow (VAR) optimization is one of the key issues. The destination of optimization is to reach the optimal status and to satisfy one or multiple objectives under some constraints. VAR optimization plays an important role in modern Energy Management System (EMS). The methods of VAR optimization, especially some new technology, are discussed. At the same time, their advantages and disadvantages are pointed out respectively.更多还原
