Voltage regulation is a main key factor for stable power system. Recent years the electronics equipment growth is rapidly increase. These electronics devices are voltage sensitive devices.
To maintain the grid system voltage equal or near to nominal level, the DVR plays major roll.
The 31 level inverter is proposed in this study to reduce number ...

The increase in consumption of low power DC appliances in home, accounts to high AC-DC conversion loss. The solar source is inherently a DC source which mainly provides the supply for DC home with low power DC appliances. This paper presents a DC Home model powered by solar source integrated with conventional backup. The power backup is provided by...

Solar energy is a promising alternative energy source for a sustainable pollution-free future. But certain factors such as solar irradiation, lack of sunlight during night hours etc. degrade or diminish the scope of solar power. To address with this problem MPPT technique is used here. Due to the requirements of high efficiency, reliability, power ...

This paper addresses a single synchronous controller (SSC) for interfaced converters with high penetration of renewable energy resources (RERs) into a low inertia power grid. The SSC is modelled based on a comprehensive dependence between each operative feature of a synchronous generator (SG) and a power electronics converter. This can properly imp...

A photovoltaic-thermoelectric (PV-TE) hybrid system can be used for efficient thermal energy utilization from the generated waste heat in PV device. In this paper, an efficient PV-TE hybrid System with intelligent power-track switching technique and thermal management based on energy conversion is proposed. To make the output power of PV-TE system ...

Grid integration of solar photovoltaic (PV) systems has been escalating in recent years, with two main motivations: reducing greenhouse gas emission and minimizing energy cost. However, the intermittent nature of solar PV generated power can significantly affect the grid voltage stability. Therefore, intermittent solar PV power generation and uncer...

With the increasing integration of PV generation in AC microgrids, it is challenging to keep the stability of system frequency due to the intermittent and stochastic nature of PVs. Thus, in order to reduce the investment and maintenance costs of storage systems, the electric utility has shown increasing interest in calling on PVs to provide frequen...

Grid-connected photovoltaic (PV) systems impose challenges like voltage fluctuations, low system inertia and power quality issues. The need to tackle these challenges led to the introduction of flexible power point tracking (FPPT), where the PV power output is controlled by an energy management system (EMS), rather than solely operating the PV syst...

Accurate and fast event identification in power systems is critical for taking timely controls to avoid instability. In this paper, a synchrophasor measurementbased fast and robust event identification method is proposed considering different penetration levels of renewable energy. A difference Teager-Kaiser energy operator (dTKEO)-based algori...
