1) High load demand on the bus.

2) High reactive power generation in the network

3) High transmission line reactance, etc.

It is paramount to note that base value of energy is 330KV. Similarly, the result of the line flows and the accompanying losses (real and reactive) for the ten (10) transmission lines are presented in table 4.

Table

Absolute real and reactive power losses are 0.09438 and 0.36970 p.u individually. Highest real power loss of 0.05070 p.u is seen on line 6-2 (Onitsha-Okpai GS) while the highest reactive power loss of 0.11579 p.u is on line 6-5 (Onitsha-Alaoji).

B. Loss Reduction and Loss Reduction Index

By compensating the reactive load at each bus, considering one bus at a time, and conducting load flow calculation, the real power loss reduction at each bus is obtained and shown in table 5.

Using equation (4) and table 6, Power Loss Index (PLI) value for ith node (bus) is obtained.
