RESEARCH OF GRID REACTIVE POWER COMPENSATION PLANNING

Reactive power balance and reasonable distribution, the system voltage stability is a critical factors affecting to the power grid safety and economic operation. The reasonable distribution of reactive power compensation capacity, is the necessary premise to realize the voltage control and reactive power control, it can not only reduce the network loss as well as improve the quality of voltage, but also to improve the stability of the system. Low of our country's power grid voltage quality, high network loss situation determines the using optimization method for power system reactive power optimization compensation is imperative, this to save power, improve the voltage quality, improve the stability of power network, and has important practical significance and remarkable economic benefit. Therefore, reactive power planning in distribution network optimization problem of research, not only has theoretical significance, but also has practical application value.
