Optimal allocation and Sizing of reactive sources in the medium voltage systems

In this paper the optimal size and location of capacitor banks for one of the medium voltage electrical networks in the existing southern region of the Libyan electrical network will be studied using Total Voltage Change Index (TVCI) method, and is calculated by summation of the mutual sensitivity values of a specific substation with respect to the other station, by using the Neplan program, to obtain an improvement for voltage profile and minimizing losses.
