Abstract. This article gives a tutorial overview of the most important issues related to the use of power electronic systems in power engineering, with respect to the urgent need for modernization of existing grids in the direction of intelligent networks. The main problems and conditions bound up with the construction of Smart Grids and the location, as well as functioning in them of the most important power electronic systems are presented here. Special attention is directed therein to the potential possibilities of so-called 'smart' transformers and V2G and V2H technologies.

“…Later, they were developed to compensate wider targets like the reactive and unbalance components, receiving then the denomination of Active Power Line Conditioner, APLC [1]. Although, the emphasis must be focused in the Unified Power Quality Conditioners, UPQC [2][3][4][5][6][7][8], which integrate in one module a combination of series and parallel APFs. Both converters are necessary because of the exposed reasons in the last paragraph, for a complete and generic load conditioning.…”

Abstract. This paper presents the obtained experimental results with a single-phase experimental prototype of a Load Compensation Active Conditioner, sLCAC. The sLCAC is composed by a series -parallel combination of active power filters, and its main objective is the global conditioning of a load against harmonic distortion. On the one hand, to isolate the load voltage v L from the harmonics in the supply voltage v S , as well as to regulate it to the nominal value. On the other hand, to improve the supply current i S , compensating the harmonic and reactive components of the load current i L . An experimental prototype has been implemented, and the obtained results are presented to support the performance of the proposed design.

“…The Unified Power Quality Conditioner (UPQC) is one of the best solutions to compensate both current-and voltage-related problems simultaneously [10][11][12]. As the UPQC is a combination of series and shunt active power filters (APFs), two APFs have different functions.…”

-The current paper presents a novel control strategy of a three-phase, four-wire Unified Power Quality (UPQC) to improve power quality. The UPQC is realized by the integration of series and shunt active power filters (APF) sharing a common dc bus capacitor. The realization of shunt APF is carried out using a three-phase, four-leg Voltage Source Inverter (VSI), and the series APF is realized using a three-phase, three-leg VSI. To extract the fundamental source voltages as reference signals for series APF, a zero-crossing detector and sample-and-hold circuits are used. For the control of shunt APF, a simple scheme based on the real component of fundamental load current (I CosΦ) with reduced numbers of current sensors is applied. The performance of the applied control algorithm is evaluated in terms of power-factor correction, source neutral current mitigation, load balancing, and mitigation of voltage and current harmonics in a three-phase, four-wire distribution system for different combinations of linear and non-linear loads. The reference signals and sensed signals are used in a hysteresis controller to generate switching signals for shunt and series APFs. In this proposed UPQC control scheme, the current/voltage control is applied to the fundamental supply currents/voltages instead of fast-changing APF currents/voltages, thus reducing the computational delay and the required sensors. MATLAB/Simulink-based simulations that support the functionality of the UPQC are obtained.
