—Loads connected to a stiff source cannot be protected from voltage disturbances using a distribution static compen-sator (DSTATCOM). In this paper, a new control-algorithm-based multifunctional DSTATCOM is proposed to operate in voltage control mode under stiff source. This scheme provides fast voltage regulation at the load terminal during voltage(More)
This paper introduces a new concept of optimal utilization of a unified power quality conditioner (UPQC). The series inverter of UPQC is controlled to perform simultaneous 1) voltage sag/swell compensation and 2) load reactive power sharing with the shunt inverter. The active power control approach is used to compensate voltage sag/swell and is integrated(More)
—The distribution static compensator (DSTATCOM) is used for load compensation in power distribution network. In this paper, a new topology for DSTATCOM applications with nonstiff source is proposed. The proposed topology enables DSTATCOM to have a reduced dc-link voltage without compromising the compensation capability. It uses a series capacitor along with(More)
—In this paper, load compensation techniques under unbalanced and distorted voltages have been discussed. Two kinds of compensation methods are considered. In the first category, synchronous detection and modified equal current strategies are used under the unbalanced but sinusoidal source voltages. In the second method, load compensation based on(More)
This paper proposes a modified four leg Distribution Static Compensator (DSTATCOM) topology for compensation of unbalanced and nonlinear loads in three phase four wire system. This proposed modified topology uses a capacitor connected in series with the interface inductor at the point of common coupling (PCC). This Modified topology requires a lower value(More)
In this paper, a new control strategy is proposed for hybrid energy storage system (HESS) for remote area power supply system consisting of PV, battery, supercapacitor (SC) and load. Since the PV generation and load demand varies continuously, batteries can undergo irregular, partial charge/discharge cycles. It has detrimental effects on battery life span(More)
—Voltage sag remains a serious power-quality (PQ) problem by being the most common and causing more economic losses. The dynamic voltage restorer (DVR) is a definitive solution to address the voltage-related PQ problems. Conventional topologies operate with a dc link, which makes them bulkier and costlier; it also imposes limits on the compensation(More)
