In recent times, interest in renewable energy-based Distributed Generation (DG) is increasing rapidly. These sources are connected to AC bus through inverter interface. During islanded mode, output voltage and frequency of should be properly regulated for stable operation it done by applying control action on inverter. The paper presents a strategy controlling output. It deals with active power...

Extensive penetration of distributed generation (DG) is one of the critical challenges near future for efficient and low carbon energy utilization in the world. Since DG installation greatly influences existing power systems, it is required to install DG with suitable location and adequate size, thus some decision-making tools for optimal DG installation are necessary. This paper presents a new...

Utility distribution grids in the US are experiencing proliferation of Distributed Generation (DG) largely due to the need to comply with goals set by Renewable Portfolio Standards (RPS), the availability of economic incentives, and technology cost reductions. Interconnecting properly-sized DG units at strategic locations in the distribution grid may lead to important benefits and improve power...

Abstract Increasing power demand and encouragement of renewable energy generation appear the importance Distributed Generation (DG). The Photovoltaic (PV) is considered a resource distributed generation. integration PV-DG unit into grid has significant effect on reducing real losses, operating costs, enhancing voltage stability. Most current researches handle this issue from point optimizing si...

This paper proposes a hybrid heuristic optimization method based on genetic algorithm and immune systems to maximize the benefits of distribution network operators (DNOs) accrued due to sizing and placement of distributed generation (DG) units in distribution networks. The effects of DG units in reducing the reinforcement costs and active power losses of distribution network have been investiga...

Amongst applications of high temperature superconductors, fault current limiters are foreseen as one of the most promising in power systems. Several topologies have been developed in the last years, taking advantage of different superconductors’ properties. Increasing distributed generation (DG) penetration, based on renewable energy, adds new short-circuit sources to electrical grids, which br...

The increase in distributed generation (DG) interferes with the energy distribution system, which may present low voltages due to voltage drops and high insertion of generation, resulting from renewable sources rural areas. These levels must be controlled comply limits imposed by rules procedures (PRODIST). This study aims evaluate rise caused DG, simulating three DG scenarios, as well simulate...

The need for energy, especially electricity is increasing along with the development of technology. An increase in electrical load and location powerplant far causes voltage drops power line losses. One solution can be chosen by adding a distributed generation (DG) to distribution network. This study aims enhance profile reduce losses based on optimal placement capacity DG-based photovoltaic (P...

INTRODUCTION In the past three years, distributed electricity generation (DG) by solar photovoltaics (PV) has leapfrogged in China, dwarfing even the growth of the Chinese solar industry itself. The year 2012 saw China’s first household DG system installed in Beijing. Two years later, as of the third quarter of 2014, DG capacity had expanded to 3.1 GW, effectively representing 16% of China’s to...

This paper presents a novel approach to multi-type distributed generation (DG) planning based on the analysis of investment and income brought by grid-connected DG. Firstly, the timing characteristics of loads and DG outputs, as well as the environmental benefits of DG are analyzed. Then, on the basis of the classification of daily load sequences, the typical daily load sequence and the typical...
