Solar photovoltaic (PV) systems are increasing in the power system day by day. These micropower sources are located in the distribution system at low voltage levels. These are also called type 1 distributed generations (DGs) as they generally supply real power to the system. Optimal location and sizing of the DGs are important as it will influence the power loss and voltage profile in the distribution network. The optimal location is found using loss sensitivity factor and sensitivity indices. The optimal size is found using successive sizing method and sensitivity factor method. Therefore, the present work develops an algorithm to solve the optimal allocation of DGs for IEEE 33 radial distribution test system. The power losses and voltage profile of the distribution network are found using forward and backward sweep methods. The power loss and voltage profile of the test system are calculated and presented without and with DGs.
