Optimal power flow for reactive power compensation increasing the cross-border transmission capacity

摘要: Increasing the Net Transfer Capacity (NTC) of tie-lines between different grid areas may lead to a decrease in cost generate electricity one area if this is more expensive than importing power from neighbouring over those tie-lines. An effective means increase cross-border transmission capacity by installing reactive compensation devices. In paper, multi-objective optimization devised that optimally locates and sizes devices grid, so net benefit increasing NTC value tie-line maximized maximum voltage stability indicator (L-index) minimized, indicating there enough margin. The genetic algorithm NSGA-II implemented perform optimization. IEEE 30-bus 14-bus test grids are used as two interconnected areas.
