Assessment of Techno-Socio-Economic Performances of Distribution Network with Optimal Planning of Multiple DGs

The presented paper provides the distribution network analysis with optimum size and site of multiple DGs utilizing real world load models like industrial, residential, commercial and constant loads using optimization techniques like BF-PS, PSO and GA optimization. The problem function is multi-objective function taken into account on the basis of distinct technical performance index of distribution power network for the assessment of the optimum place and size of DG. The technical, social and economic performance analysis of system comprises of various parameters assessment related to these performances. The system performance like power loss (active & reactive), reliability, voltage profile, pollutant and carbon emission are considered. Subsequently, the economic performance like system total cost, loss cost, ENS cost and benefit-cost are reported. The pollutant emission (CO2, NOx and SO2 etc.) and the particulate matter (PM) also known as particle pollution are analyzed as social parameter for the system planning. The presented work is carried out with the IEEE 33-bus radial distribution network. Afterward, the analysis of aforesaid performances and parameters (social, technical and economic) for distribution system shows the effective results including DGs with practical loads using different optimization techniques.
