Prospects of Using DG with Effective Energy Storage System for the Reduction of Line Loss in Distribution Network

In conventional Electric Power system, centralized power generation plants are used which are far away from the load center. Therefore for the transmission of power from the generating station to load center causes line loss, which varies in valleys and peaks of the load curve. Distributed Generation (DG) can be used for the reduction of the line losses. In this paper, it is analyzed that Proper placement and sizing of the DG has great impact on the system line loss reduction. It is further shown that more than one DG of same size at different locations has great impact upon the reduction of line losses and also the N-1 contingency is increased. Moreover, some effective energy storage system is added to the radial distribution feeder due to which the peaks and valleys of the load curve is flattened (Straight Line). Simulation results shows that Valleys and Peaks in load curve have more losses compared to the straight line load curve which is ideal. In order to show the effectiveness of the proposed scheme, 11 kV radial Distribution feeder is modeled in Matlab. Comparison of the results shows that line losses are reduced by employing the proposed method.
