Optimal Voltage Control Strategy for Voltage Regulators in Active Unbalanced Distribution Systems Using Multi-Agents

Impedance Control of Robots Using Voltage Control Strategy Revisited

In this note, we show that the impedance control strategy proposed in the paper is not feasible from practical implementation point of view. Next, a robust impedance controller is proposed for electrically driven robots using Fourier series (FS). The fact that robots' actuators have limited voltage is also considered in controller design procedure. In comparison with other impedance controllers...

A model-based PDPC method for control of BDFRG under unbalanced grid voltage condition using power compensation strategy

Brushless doubly fed reluctance generator (BDFRG) has been recently suggested as a wind generator. Different control methods are presented in literature for the BDFRG, but there is a gap on control under unbalanced grid voltage condition (UGVC). This paper presents a predictive direct power control (PDPC) method for the BDFRG under UGVC. The proposed PDPC method is based on power compensation s...

Optimal Planning of Voltage Controlled Distributed Generators for Power Loss Reduction in Unbalanced Distribution Systems

This paper proposes a novel heuristic algorithm that aims to determine the best size and location of distributed generators in unbalanced distribution networks. The proposed heuristic algorithm can deal with the planning cases where power loss is to be optimized without violating the system practical constraints. The distributed generation units in the proposed algorithm is modeled as voltage c...

Multi-Agent System Based Distributed Voltage Control in Distribution Systems

Mitigation of voltage sags/swells unbalanced in low voltage distribution systems

The main problems of the power quality like voltage sags/swells in low voltage distribution systems and on the transmission side due to sensitive loads, the terminology used for the compensation devices is different. Dynamic Voltage Restorer (DVR) is one of the equipments for voltage disturbance mitigation in power systems. It is installed between the incoming supply and the sensitive loads to ...
