Optimal shunt compensation for unbalanced linear loads with nonsinusoidal supply voltages

Document Type



This paper presents a solution to an optimal three-phase compensator for power factor correction and load balancing in case where a nonsinusoidal voltage source is feeding a linear unbalanced load. An objective function which consists of energy loss and compensator cost with load balancing constraints is formulated. A numerical algorithm that converges directly to the global solution to the problem is proposed. Results of special cases found in the literature are derived from simplifications of the general case considered. Simulation results show that optimal compensation found by neglecting harmonic components may lead to severe resonance problems.
