The Reactive Power Compensation Planning for N-1 Line Outage Based on Line Fault Betweenness

An inappropriate compensation capacity can cause oscillation or even collapse of the grid. This paper focus on the RPP problem considering single line outage in the grid. Firstly, the line fault betweenness (LFB) is proposed to identify the preoutage and post-outage impact on vulnerable lines. Then,...

Description
Summary:	An inappropriate compensation capacity can cause oscillation or even collapse of the grid. This paper focus on the RPP problem considering single line outage in the grid. Firstly, the line fault betweenness (LFB) is proposed to identify the preoutage and post-outage impact on vulnerable lines. Then, considering the cost and power quality of the grid, a multi-objective optimization is adopted to analysis the result of compensation planning and solved by the multi-objective genetic algorithm and F1-scores. Finally, the IEEE-39 test system is employed to illustrate the important lines with LFB ranking and the decision of reactive power compensation planning. The compensation result reveals the improvement on power factor of generators and load voltage offset reduction.
