Any electrical power system consists of wide range of electrical, electronic and power electronic equipment in commercial and industrial applications. Since most of the electronic equipment is nonlinear in nature these will induce harmonics in the system, which affect the sensitive loads to be fed from the system. One among the many compensating devices is Unified Power Quality Conditioner (UPQ...

<span lang="EN-US">The intensive use of non-linear loads is further contributing in the increase power quality problems. They cause voltage distortions and current harmonics an electrical distribution network. To minimize these problems, unified conditioner (UPQC) used. The intermediate circuit this filter can deviate from its source during a transient event harmonic disturbance (voltage ...

This paper mainly deals with the regulation of voltage at wind farm (WF) terminals and the improvement of power quality and WF stability in a WF to Weak-Grid connection. In facilities with moderated power generation, the WF are connected through medium voltage (MV) distribution headlines. A situation commonly found in such scheme is that the power generated is comparable to the transport capaci...

This paper proposes a fuzzy logic based new control scheme for the Unified Power Quality Conditioner (UPQC) for minimizing the voltage sag and total harmonic distortion in the distribution system consequently to improve the power quality. UPQC is a recent power electronic module which guarantees better power quality mitigation as it has both series-active and shunt-active power filters (APFs). ...

Unified power quality conditioners (UPQCs) allow the mitigation of voltage and current disturbances that could affect sensitive electrical loads while compensating the load reactive power. This paper deals with unified power quality conditioner (UPQC), which aims at the integration of Series-active and shunt-active power filters. The main purpose of a UPQC is to compensate for voltage Imbalance...

The increasing demand of electric power is giving an emphasis on the need for the maximum utilization of renewable energy sources. On the other hand maintaining power quality to satisfaction of utility is an essential requirement. In this paper the design aspects of a Unified Power Quality Conditioner integrated with photovoltaic system in a distributed generation is presented. The proposed sys...

In this paper, based on a benchmark the performance of Unified Power Quality Conditioner (UPQC), improvement is presented comparatively by using Proportional Integrator (PI)-type controllers optimized Grey Wolf Optimization (GWO) computational intelligence method, fractional order (FO)-type differential and integral calculus, PI-type controller in tandem with Reinforcement Learning—Twin-Delayed...

The increasing number of electricity consumers results in power quality problems the distribution system. Solar photovoltaic integrated unified conditioner (UPQC-PV) is a widely adopted device that can improve system's voltage and current quality. This paper presents an optimal design performance analysis with double-stage solar system (UPQC-PV). A technique based on sequence component detectio...

This paper proposes a neuron adaptive harmonic detection algorithm which can adaptively,rapidly and precisely calculate the voltage and current reference signals in presence of the system frequency variation, according to which, a Double Integration Control (DIC) strategy is applied in Unified Power Quality Conditioner (UPQC) as an interface between the hybrid power system and the load.Generall...
