Integration of Stand-Alone Controlled Active Power Filters in Harmonic Power Flow of Radial Distribution Networks

Utilization of active power filters (APFs) is the most efficient method to reduce harmonic pollution in distribution networks. Previous approaches utilized APFs integrated control schemes based on broad data-gathering systems. Since a system not available practical networks, previously proposed may readily be implemented. This paper presents utilization stand-alone controlled (SACAPFs) radial Utilizing with decreases implementation costs and complexity by making them autonomous independent systems, which are complicated expensive applications. In this paper, single SACAPF modeled as dependent current source where its injection equal amplitude but opposite phase compared content passing through point common coupling (reference current). Due presence both linear nonlinear loads network, reference changes after SACAPF, so it necessary modify until reaching constant value current. considered via an iterative procedure modeling scheme. Operation multiple SACAPFs handled using backward priority list. Simulation results IEEE 18-bus test show proper operation systems for implementation. Furthermore, optimal allocation performed 33-bus network 9-bus discussed APFs.
