Abstract:
With the progressive growth of load demand, it has become more challenging
to manage load system performance over different time horizon via fixed load
allocation approach leading to enormous power loss. The reason is that power
loss increases with fixed load allocation and active power loss directly impacts
system economics. This research work aimed at minimizing power losses in a
transmission system thereby improving the quality and reliability of power
supply. In this study, a new load allocation model is presented to meet the
increasing load demand with minimal active power loss. First, the bulk power
network was partitioned into three areas, Western, Southern and Northern area
respectively. Specific distribution indices and weighting factors were then
assigned to the partitioned bulk power network. The partitioning became
necessary to prioritize each partitioned cluster and investigate their
performance in relation to one another. The performance of the network was
assessed under a determined percentage load increase and generator
contingency based on power flow simulation using a proprietary software
known as NEPLAN. The effectiveness of the method was validated on the
Nigerian 39-bus bulk power network. The selected model resulted to a
percentage decrease of up to 59.5% in active power loss on the modelled
network
