Tariff power meter divides the day into different electricity price periods and records energy consumption. It encourages rational electricity use and peak load shifting to optimize energy allocation and stabilize power systems. It can change consumers' electricity habits by displaying daily power consumption and cost savings. Supporting systems and education are necessary for effective ...
The Power Quality problems of an electrical distribution network are often generated locally within the structures and can depend on various situations, such as, for example, construction works, switching on high loads, faulty distribution components and particular basic electrical disturbances. Furthermore, external causes such as atmospheric events (hurricanes, lightning, snow, ice and ...
With the increasingly widespread use of sensitive electrical and electronic equipment, it is essential to have a “clean” and stable mains power supply to protect and make critical applications reliable. IREM Steroguard Line Conditioners represent the solution for most of the disturbances coming from the electrical ...

An adaptive hysteresis current and voltage control technique for controlling Unified Power Quality Conditioner (UPQC) is proposed in this paper. The novelty of the proposed method is the series and shunt active power filters (APF) present in the UPQC has been controlled by the separate adaptive controllers for reducing the voltage and current perturbations. Here, the adaptive control technique ...
Whether you need basic preparedness equipment or something portable that you can take you on your family camping and wilderness trips, Yamaha generators are the perfect choice for all kinds of additional or alternative power source requirements. Portable gensets from Yamaha are among the most powerful in the market today. The EF series, for one, features compact versions that offer as much as ...
Net metering is a concept that has been talked about extensively in the world of solar. But, what exactly does it mean for you and when will it come to ...
This paper presents a three-phase shunt active power line conditioner (APLC) for harmonics and reactive power compensation to enhance the power quality. The compensation process is based on sinusoidal extraction control method, which consists of positive-sequence voltage detector to regulate the distorted supply ...
Unified power quality conditioner (UPQC) is a combination of series and shunt active power filters with a common DC link. This device is used to enhance power quality by injecting required amount of Volt–Ampere (VA) into the system. In view of the cost effectiveness, it is desirable to have VA loading of UPQC without compromising the compensation capability. This paper presents a methodology to ...
This paper presents an innovative implementation of the recursive Gauss-Newton (GN) algorithm for extraction of the common current quality problems such as the current harmonics and current fluctuation. This paper introduces also the utilisation of the adaptive notch filters to efficiently track the unknown frequencies of the current disturbances. The paper exhibits the mitigation results for ...
The renewable sources of energy are being connected to the local distribution system/local grid leading to embedded generation. As these sources are intermittent in nature, they impose technical challenges in the power system operation which include power quality related problems of local grid. The performance of the system has to be evaluated while connecting these sources to the local ...
In recent years unified power quality conditioner (UPQC) is being used as a universal active power conditioning device to mitigate both current as well as voltage harmonics at a distribution end of power system network. The performance of UPQC mainly depends upon how quickly and accurately compensation signals are derived. The artificial neural network (ANN) trained with conventional compensator ...
The key issue to the widespread of distributed generation (DG) is the ability to safely, reliably and economically interconnect new energy sources with the existing distribution network 'utility grid'. With the rising prices of petroleum fuel sources, a high expected penetration of renewable energy sources (RES) such as wind and solar as part of the emerging DG fuel resource are expected to be ...
Improving power quality for sensitive load by a Unified Power Quality Conditioner (UPQC) in a distributed generation system is presented in this paper. The power balance of a UPQC, consisting of back-to-back connected series and shunt Active Filters (AF), is analysed. Based on the analysis a novel control scheme is established in a 2-phase Synchronous Rotating d-q Frame (SRF). In this control ...
The paper summarises the refereed contributions of seven articles reviewed for publication in the IJETP – Special Issue on "Reactive compensation for wind farms". The main goal of the special issue is to provide a forum to exchange information on the reactive power compensation requirements for wind farms and introducing possible price mechanisms for today's deregulated power industry. ...
In this paper, modelling and simulation of a grid connected variable speed wind energy conversion system (VSWECS) with reduced switch count power converter is presented. The system consists of a permanent magnet synchronous generator (PMSG), two pulse width modulated B-4 power converters and a maximum power point tracker (MPPT). Mathematical models of each element of the system are developed ...
