With an increase of non-linear load in today’s electrical power systems, the rate quality drops and voltage source frequency deteriorate if not properly compensated with appropriate device. Filters are most common techniques that employed to overcome this problem improving quality. In paper improved optimization technique filter applies system is based on a particle swarm using artificial neura...
