Renewable energy resources (RES) are being increasingly connected in distribution systems utilizing power electronic converters. This paper presents a novel control strategy for achieving maximum benefits from these grid-interfacing inverters when installed in 3-phase 4-wire distribution systems. The inverter is controlled to perform as a multi-function device by incorporating active power filt...

With the rapid growth of renewable sources energy, single-phase rooftop photovoltaic inverters (SIs) connected to distribution network have received widespread applications in recent years. In such a network, asymmetric fault problems are likely occur and small-signal stability during faults becomes an important issue. The existing papers analyzed sequence impedance related issues three-phase t...

In this paper, a locational marginal pricing algorithm is proposed to control the voltage in unbalanced distribution grids. The increasing amount of photovoltaic (PV) generation installed in the grid may cause the voltage to rise to unacceptable levels during periods of low consumption. With locational prices, the distribution system operator can steer the reactive power consumption and active ...

This paper discusses grounding practices used on electric distribution systems above 600 Volts. In particular, the paper concentrates on the three-phase fourwire, multi-grounded neutral system that is extensively used in North America. The paper addresses the benefits of the multi-grounded power system and makes comparisons with other grounding system designs including ungrounded; three-wire si...

The imbalance of phase loads is a natural negative property low-voltage three-phase four-wire network due to uneven connection the phases and difference in individual consumer demand for electricity. nodes leads decrease quality electricity, overestimated technical losses current overloads one power lines. In paper, balancing performed using heuristic algorithm based on average hourly readings ...

This paper presents an analysis on the unified Power quality conditioner (UPQC) to improve the electric power quality at distribution levels. Conventional power quality mitigation equipment is a providing to be poor for an increasing number of applications. Different approaches in compensation and recent developments in fields. Single modern and very promising solution that deal with both load ...
