Reassessment of Power Losses and Enhancement of Techno-Economic Feasibility in a Radial Distribution System

A shift toward energy sources from distribution generation has been established as a consequence of the excessive energy consumption that emerges from a demographic growth. Such a consumption leads to an increased power demand in addition to accelerated environmental effects. Thus, the contemporary power system has now become more susceptible to various power losses. As a consequence, system stability of power grid is paramount to distribution modeling. A number of analytical, heuristic, and simulation-based approaches are being suggested by the researchers in order to improve precision and optimized results for the best sizing and placement of Distribution Generation to the electric grid. In this paper, a radial distribution test setup for the IEEE 33 bus with type-1 distributed generation which exclusively supplies for which mostly the real power is assessed. Real power-loss minimization and voltage stability are evaluated along with determining the efficient allocation of DG for integration of type-1 DG to the former IEEE-33 bus system using Particle Swarm Optimization (PSO) and Genetic algorithm (GA) using Matlab. Also, techno-economic feasibility is computed for the afore said system. The assessment results revealed that the reduction of the real power loss due to integration of multiple DG causes a notable rise in the voltage profile.
