With system, factor can be improved near to unity. The selected system mainly feeding vital loads an Educational Institution. In this paper, study is analyzed ...

Increased integration of photovoltaics (PVs) systems and charging stations for electric vehicles (EVs) has led to a substantial increase in the level voltage unbalance beyond acceptable limit. Ordinary regulation devices such as on-load tap changers (OLTCs) distribution static synchronous compensator (DSTATCOM) are sometimes incapable adequately addressing this issue without proper coordination...

This paper proposes a new stochastic framework based on the probabilistic load flow to consider the uncertainty effects in the Distribution Static Compensator (DSTATCOM) allocation and sizing problem. The proposed method is based on the point estimate method (PEM) to capture the uncertainty associated with the forecast error of the loads. In order to explore the search space globally, a new opt...

Abstract This paper presents the shunt compensation performance of quasi-Z-source inverter (QZSI) and back to connected QZSIs (BB-QZSI) address power quality (PQ) issues in three-phase three-wire utility network (PUN). Generally, these PQ are poor voltage regulation, low factor (PF), source current distortion, unbalanced voltage, etc. The proposed BBQZSI-based distribution static compensator (D...

The distribution systems are facing severe power quality problems due to the large number of three phase and single phase linear, non-linear loads. These loads may be supplied from three-phase ac mains with neutral conductor. This creates excessive neutral current, high reactive power and harmonic current burden, load unbalancing, poor voltage regulation, etc. A three-phase fourwire distributio...

Because of the increasing growth Electric Vehicle (EV) in India, more electricity is required to power such vehicles. It also gaining popularity because its low maintenance, improved performance, and zero carbon impact. As usage electric vehicles grows, distribution system’s performance impacted. an outcome, reliability system (DS) dependent on position vehicle charging station (EVCS). The fund...

The enhancement in electric power quality using a single-stage solar PV integrated Unified Power Quality Conditioner (UPQC) has been discussed this paper. UPQC is the combination of Distributed static compensator (DSTATCOM) and Dynamic Voltage Restorer (DVR) having common DC voltage supply link. DSTATCOM compensates for load current associated problems like factor improvement, even odd harmonic...

The paper introduces the modified UPQC topology with reduced switching losses. UPQC is a versatile custom power device which consists of two inverters connected back to back and deals with both load current and supply voltage imperfections. It can simultaneously perform as shunt and series active power filters. The series part of the UPQC acts as Dynamic Voltage Restorer (DVR). It is used to ma...
