An accurate forecasting of PV output is essential to improve real-time control performance and to reduce possible negative impacts. For an energy management system (EMS) of distributed energy resources, accurate forecasting of solar irradiation and thus PV power output can reduce the impact of uncertainty for PV power generation, improve system reliability, and increase the penetration level of the...
Particle Swarm Optimization (PSO) technique has been applied for multi-junction solar cell system. The solar panels are made up of different materials and give constant output from Boost converter. The main aim of PSO is to find out duty cycle to the Boost converter to maintain constant output voltage irrespective of power produced by solar panels. A detailed simulation of the proposed method has...
Solar Photovoltaic (PV) exploitation is a significant renewable energy source. The energy converted directly from sunlight through PV panel is not steady due to different solar intensity. Maximum power point tracking (MPPT) is used extract maximum power from the solar panel, high-performance soft computing techniques can be used as a maximum power point tracking techniques. This paper proposes fuzzy...
This paper analyzes the feasibility study of wind and solar PV based microgrid installation in an educational institution, with grid uncertainty. The idea of bringing out “Green Campus” in our Academic Institution, situated very close to east coast of India (Chennai City) is achieved by implementing a microgrid with available renewable sources such as solar and wind which is designed optimally using...
Microgrids integrate distributed energy resources to provide reliable, environment friendly and economic power to small/medium sized urban communities or to large rural areas. Due to the existence of generators at all levels of the distribution system and two distinct operating modes, i.e. grid connected and islanded modes, the fault currents in a system vary substantially. With appropriate relay...
In this era of energy crisis, renewable energy is the most promising solution to man's ever increasing energy needs. But the power production by these resources cannot be controlled unlike in thermal plants. As a result, standalone operation of renewable energy is not reliable. Hence grid-connection of these along with conventional plants is preferred due to the improved performance in response to...
Electromagnetic transient studies have always played an essential role in the analysis of electrical power systems. They provide priceless information relating to the behaviour of the system in the event of different forms of transient phenomena, which can hardly be achieved by other means. In this paper, an electromagnetic transient model of Fixed Capacitor/ Thyristor Controlled Reactor (FC-TCR)...
In recent years, energy, environment, deregulation of power utilities have delayed the construction of both generation facilities and new transmission lines. These problems have necessitated a change in traditional concepts and practices of power systems. There are emerging technologies available, which can help electric companies to deal with above problems. One of such technologies is Flexible AC...
