Voltage violations are the main problem faced in distribution networks (DN) with a higher penetration of inverter-based generations (IBG). Active and reactive power control from smart inverters (SI) can mitigate such violations. Optimal flow (OPF)-based provides more accurate operating set points for coordinated operation SIs. Therefore, this paper presents three-phase OPF-based on SI-enriched ...

Insertion of distributed micro and mini-generation systems in the Electrical Power System has shown high growth recent years, with emphasis on photovoltaic generation. However, it is necessary to ensure that efficiency electrical power quality indices are within acceptable limits, view penetration generation can cause a lot problems network, mainly voltage deviation. Therefore, several studies ...

Optimal Volt/VAR control (VVC) in distribution networks relies on an effective coordination between the conventional utility-owned mechanical devices and smart residential photovoltaic (PV) inverters. Typically, a central controller carries out periodic optimization sends setpoints to local of each device. However, instead tracking centrally dispatched setpoints, PV inverters can cooperate much...

This paper proposes attention enabled multi-agent deep reinforcement learning (MADRL) framework for active distribution network decentralized Volt-VAR control. Using the unsupervised clustering, whole system can be decomposed into several sub-networks according to voltage and reactive power sensitivity relationships. Then, distributed control problem of each sub-network is modeled as Markov gam...

In an active power distribution system, Volt-VAR optimization (VVO) methods are employed to achieve network-level objectives such as minimization of network losses. The commonly used model-based centralized and distributed VVO algorithms perform poorly in the absence a communication system with model measurement uncertainties. this paper, we proposed model-free local control approach for that d...

Unequal reactive power sharing amongst distributed generators (DG) is a significant concern while operating droop based microgrid. The reasons for this unequal include the difference in feeder impedances, uneven distribution of loads and DGs terms size locations. In article, mixed-integer linear programming (MILP) problem applicable microgrid has been proposed to achieve proportional maintainin...

Modern distribution networks face an increasing number of challenges in maintaining balanced grid voltages because the rapid increase single-phase distributed generators. Because proliferation inverter-based resources, such as photovoltaic (PV) networks, a novel method is proposed for mitigating voltage unbalance at point common coupling by tuning volt–var curve each PV inverter through day-ahe...

This paper describes the design of a fully differential CMOS amplifier for clipping control circuit. The amplifier with specification of low settling time less than 5ns, high dynamic range above 90dB and low power supply of 3 volt is designed and realized in a 0.35 μm CMOS process with 3 volt power supply. Simulation confirm the presented design.
