This paper proposes a voltage-rise-suppression strategy with a power quality compensator for a roof-top home solar power system (HSPS) connected to the point of common coupling (PCC) in single-phase three-wire distribution feeders (SPTWDFs). The proposed reactive power control and power quality compensation strategy uses only a constant dc-capacitor voltage control, which is always used in grid-connected inverters. No calculation blocks of the reactive and unbalanced active components of the load currents are necessary. Thus, the authors provide the simplest algorithm to suppress the voltage rise at the PCC with power quality compensation. The basic principle of the constant dc-capacitor voltage-control-based strategy is discussed in detail. The instantaneous power flowing into the HSPSs shows that the predefined power factor of 0.9, a value that conforms to the Japanese regulations, is achieved with improved-quality source-currents of domestic consumers connected to SPTWDFs, suppressing the voltage rise at the PCC. A digital computer simulation is implemented to confirm the validity and high practicability of the proposed control algorithm for HSPSs using a typical SPTWDF model in Japan. Simulation results demonstrate that the proposed control method for the roof-top HSPS suppresses the voltage rise at the PCC, improving the source-side power quality.
