Integration of Distributed Generation in Medium Voltage Distribution Network Using Fuzzy Logic Controller for Demand Side Management

In this research simulations have been carried out on IEEE 13 node test distribution feeder to show the impact of adding distributed generations on voltage profiles along with the changing loads in medium voltage distribution network using Power World Simulator 17 software. Equations of power line loss coefficients have been determined to approximate the numerical values of test feeder to compare the best and worst case. Voltage profile and hosting capacity for the case studies have been determined using the data obtained from the simulations. A fuzzy logic controller has been proposed in the 13 node test distribution feeder to determine the amount of DG output to be added in the network on the basis of power demand gap and time of the day. Another fuzzy logic controller is proposed to select the bus where the distributed generations have to be connected using the input of DG amount needed to be installed and distance of generation from the distribution transformer in the distribution network. Fuzzy logic toolbox of Mat lab has been used to perform the simulation.
