A micorgrid is a small size distribution grid that integrated various on-site distributed energy sources to satisfy the local energy demand. A microgrid can either be connected to the main utility grid or operate in islanded mode. The technical, economic and environmental benefits associated with microgrids have led to extensive research in this area. However, development of advanced planning and...
PV based distributed generators are inverter based and employ a switching scheme to inject power into the grid. The most common and commercially used technique involves the Pulse Width Modulation (PWM) controlled technique. Although PWM based technique is widely used, it is not affirmative to conclude that hysteresis controlled technique could be dismissed completely. A comparative evaluation and...
As more number of distributed generators like PV are penetrated into the power system network, the interaction of the filter elements associated with PV inverter and rest of the distribution system elements on network resonance needs to be investigated. Although the recent investigation of network resonance is focusing only on distributed generators like PV, the impact from distribution lines coming...
The increase in penetration levels of distributed generators like PV and Wind in a distribution system makes the IEEE 519 standard to be a vital aspect towards power quality. The network resonance has been described by IEEE 519 as a major contributor towards the harmonic distortion. Non-linear loads such as transformers, machines, silicon-controlled rectifiers (SCRs), solid state devices, power transistors,...
The problems associated with the harmonics needs more attention as more number of distributed generators like PV and wind are integrated into a distribution system. Although the integration presents a lot of benefits, satisfying the needs of local load requirements by reducing the line losses and facilitating congestion management, the problems of power quality that impact the distribution system...
Photovoltaic energy (PV) is one of the cleanest forms of renewable energy. The popularity of this technology has been widely recognized with the incentives provided by the governments of various countries across the globe. Day by day, the growth rate of PV is steadily increasing. Renewable energy resources like PV are interfaced with power electronic inverters to enable its interconnection to the...
In a deregulated market environment, the calculation of market power is one of the top priorities of the bodies involved in the market. The bodies generally involved such as the Generation companies (GENCOs), Distribution companies (DISCOs) look towards maximizing profit whereas the RTO/ISOs look to attain a zero market power environment. In this paper, Must Run Share and Nodal Must Run Share (NMRS)...
Distribution system is one of the major sectors of the power system in a country. In this system, the maximum amount of loss occurs on the distribution side thus a complete analysis of the amounts of losses that each component has in the distribution system has to be made. Loss reduction initiatives in distribution systems have been activated due to the increasing cost of supplying electricity, the...
Integration of Renewable Energy like Wind and Solar has started paving ways for a green environment with the introduction of Schemes like Feed in Tariff Program. Particularly North Europe, Germany, Spain, USA, Canada, China, and India have shown a strong achievement in expanding the wind energy systems. This has given a new dimension in the area of research pertaining to Power Electronics applications...
Technological advancement in renewable energy systems and government incentives like Feed In Tariff Program for green electricity generation is motivating utilities around the world to upgrade their existing distribution system infrastructure in order to accommodate increased wind power and photovoltaic (PV) solar power based distributed generation (DG) systems. This paper presents the effect of Distributed...
The rapid increase in the power generation from various emerging wind and solar projects are proving to be highly beneficial and eco-friendly. But adding a new renewable resource onto an existing transmission network has become a challenge. The existing transmission network should be in a position to accept the newly generated power, when a renewable source is integrated onto it. This paper explains...
PV Solar Farm/Plant produces real power during the day and is completely idle in the night and also during daytime when the sunlight is not present. This paper presents a Novel Concept of 24 Hour utilization of a PV Solar Plant in a Distribution Feeder for Line Loss Reduction and the Savings obtained during this Loss reduction and also the demonstration of Voltage Profile Improvement in a Distribution...
This paper presents the fourth part of the Bibliography of FACTS technology for 2009 and 2010. It provides a listing of various journal and conference papers in this area.
PV solar farms produce power during the day and are completely idle in the nights. This paper presents a novel utilization of a PV solar plant as STATCOM in the night for load reactive power compensation and voltage control. This STATCOM functionality will also be available to a substantial degree during the daytime with the inverter capacity remaining after real power production. The local distribution...
