Active filters have proven to be more effective than passive techniques to improve power quality and to solve harmonic and power factor problems due to nonlinear loads. This paper proposes a control scheme based on the instantaneous active and reactive power. The inverter of this active filter is a three-phase, two-level converter. Space vector technique is used as modulators and pattern genera...

In I/Q processing receivers, matching the amplitudes and phases of the Iand Q-branches is of major concern. In practise, matching can never be perfect in the analog front-end which results in insufficient rejection of the image frequency band. As a consequence, the desired channel signal is interfered by up to 50-100 dB stronger image signal and some kind of imbalance compensation is needed. In...

Studies in the behavioral ethics and moral psychology traditions have begun to reveal the important roles of self-related processes that underlie moral behavior. Unfortunately, this research has resulted in two distinct and opposing streams of findings that are usually referred to as moral consistency and moral compensation. Moral consistency research shows that a salient self-concept as a mora...

− The study presented in this paper aims to develop a new method for active and reactive power balancing in a four-wire stand-alone microgrid (MG), which feds single phase loads. Two unbalance compensation controllers are used, for active and reactive powers. The compensation is based on a dump load (DL) and a static compensator (STATCOM), which ensure the balance of the active and reactive pow...

The D-STATCOM is a shunt connected FACTS device which supplies reactive power to the load to improve the voltage stability of the load busses. The D-STAT COM in multi bus system is capable of reducing the losses and improving the voltage regulation.This work deals with comparison of Push Pull and Voltage Inverter based D-STATCOM for multi bus system. Eight bus system is modeled using the elemen...

For multi-objective optimal reactive power dispatch (MORPD), a new approach is proposed where simultaneous minimization of the active power transmission loss, the bus voltage deviation and the voltage stability index of a power system are achieved. Optimal settings of continuous and discrete control variables (e.g. generator voltages, tap positions of tap changing transformers and the number of...

Optimal Reactive Power Dispatch (ORPD) is a multi-variable problem with nonlinear constraints and continuous/discrete decision variables. Due to the stochastic behavior of loads, the ORPD requires a probabilistic mathematical model. In this paper, Monte Carlo Simulation (MCS) is used for modeling of load uncertainties in the ORPD problem. The problem is formulated as a nonlinear constrained mul...

Power quality in distribution systems has been attracting an increasing interest during recent years. Research studies include the quality of voltage supply with connected to the same point of common coupling (PCC). Utility distribution networks, sensitive industrial loads and critical commercial operations suffer from various types of outages and service interruptions which can cost significan...
