ABSTRACT: Nowadays the optimal allocation
of distributed generation (DG) in the distribution network becomes the popular research
area in restructuring of power system. The capacitor banks introduced in the distribution
networks for reactive power compensation also have the capacity to minimize the
real and reactive power losses occurred in the system. Hence, this research integrates
the allocation of renewable energy DG and capacitor banks in the radial distribution
network to minimize the real power loss occurred in the system. A two-stage methodology is used for
simultaneous allocation of renewable DG and capacitor banks. The optimum location
of renewable energy DG and capacitor banks is determined using the distributed generation
sitting index (DGSI) ranking method and the optimum sizing of DG and capacitor banks
is found out for simultaneous placement using weight improved particle swarm optimization
algorithm (WIPSO) and self adaptive differential evolution algorithm (SADE). This two-stage methodology reduces the
burden of SADE and WIPSO algorithm, by using the DGSI index in determining the optimal
location. Hence the computational time gets reduced which makes them suitable for
online applications. By using the above methodology, a comprehensive performance
analysis is done on IEEE 33 bus and 69 bus RDNs and the results are discussed in
detail.
