Abstract

Background/Objectives: This paper is to determine the best location for siting and filling of multiple DER’s generators to support reduced power loss and cheaper power transfer as demonstrated in IEEE 30 bus standard system with the help of Power World Simulator Package. Methods/Statistical analysis: Analysis of Sensitivity in power losses in terms of DER’s size and DER’s siting has been performed by using Newton Raphson method. The proposed interconnected model gives efficient power transfer with respect to changes in power losses by solar power systems current injection in grid. Findings: After connecting multiple solar power systems to an electrical grid system, there by deciding the minimizing power losses and maximizing profit margin to increasing regulation and performance of the system. Simulation results shows the economical dispatch for final siting of solar power system as mentioned in IEEE 30 bus system and to operate within limits of voltages and currents ratings. Application/Improvements: In order to develop new solar power generation plant to interconnect electrical grid. Single line drawing of 2MW solar PV power plant added to 33 kV Nagaladinne feeder line Andhra Pradesh DISCOM, India. The whole distribution system network, and programs offered by governments has contributed to an increase in the number of distributed energy resources (DERs) in commercial and domestic electrical power generating units.
