Analysis of series compensation from different aspects

Abstract

This paper introduces methods to find the location and size of series capacitor. The methods use reactive power loss sensitivity index (RPLSI) to find the location of series capacitor, and calculate the degree of series compensation to maximize the power flow. It is also shown that series compensation can be represented in Z/sub bus/ by adding a new parallel line. Finally the line flows of the compensated system is calculated using the base case power flow of the original system and the decoupled form of Jacobian matrix.
