AU-K. CHANDRAM AND CH. VENKATA RAO
AB-In this paper, the optimal locations of particular sizes of Type -1 Distributed Generators (DGs) is determined by Direct Search Algorithm to obtain the maximum possible reduction in power loss. Type-1 DG injects both active and reactive powers. The algorithm searches for all possible locations in the system for a particular size of DG and places it at the bus which gives maximum reduction in Total power loss. The optimal sizes of DGs are chosen to be standard sizes i.e., discrete sizes of DGs are considered. The algorithm is tested on 33 bus and 69 Bus Radial Distribution Systems. The loss reduction obtained in this paper for the 33 bus and 69 Bus Test Systemsare highest compared to the other techniques as reported in the literature. Power factor of the DG is considered in this study is 0.85.
On 33 bus system, without placement of DGs the loss is 211 kW whereas after placement it is 13.55 kW. There is a reduction of 93.57% in the losses. Before placement of DGs, the power loss is 5.37% of the total power supplied by the slack bus. After optimal placement by the DSA algorithm, the totalpower loss is 0.36% of the total power supplied by the system.On 69 bus system, without placement of DGs the loss is 225 kW whereas after placement it is 5.75 kW. There is a reduction of 97.44% in the losses. Before placement of DGs, the power loss is 5.36% of the total power supplied by the slack bus. After optimal placement by the DSA algorithm, the Total power loss is 0.15% of the total power supplied by the system It is implemented using MATLAB/Simulink.
