This paper presents a three-phase Active Power Conditioner to improve power quality in microgrids based on renewable energy. A microgrid is a weak electrical grid which can be easily subject to disturbances. The Active Power Conditioner (APC) presented in this paper acts as an interface between renewable energy sources and the AC bus of a microgrid and uses an improved control strategy, which makes...
UPQC is the powerful tool to settle the power quality problem. This paper presents a novel control strategy of UPQC. It can be used in the system that voltage and current are unbalanced or/and with harmonics. Only the voltages and the currents measured are used in the control, it avoids the transformation like Park transformation of dq0 theory which is based on the instantaneous reactive theory. Simulation...
