OPTIMAL REACTIVE POWER PLANNING OF ELECTRICAL POWER SYSTEM

Li Linchuan\ Wang Jianyong\ Chen Liyi\ Song Wennan Department of Automation,Tianjin University,Tianjin,300072\ China  
The mathematical model of optimal reactive power planning which has been estabilished in this paper,uses the sum of active power lose money and minimize investment in new adding VAR equipment which has been divided in each year as the objective function.Equality constraints consist of three different load operation conditions-light,normal and heavy,so do unequality constraints.All the methods make the model more comply with the actual situation and avoid the onesidedness of single load operation condition.Based on the theory of decomposition and concert,we resolve the complex mathematical model into three submodels under right,normal and heavy load operation conditions,the investment of new adding VAR equipment is considered under heavy load operation condition.We coordinate three models by using heavy load loss time.Therefore,various operating conditions are considered so that the result is precise and the algorithm is simple and can be easily realized.
