Electricity generated from renewable sources, such as solar and wind power, offers enormous potential for meeting future energy demands. But access to solar and wind energy is intermittent, whereas electricity must be reliably available for 24 hours a day: Even second-to-second fluctuations can cause major disruptions that cost tens of billions of dollars annually. Electrical energy storage dev...

The presented paper is a techno-economic feasibility study to use solar energy as a renewable energy to power the Passive Optical Network (PON). This discussion focuses on the requirements and sources of power for the active components of optical access networks. To ensure continuous reduction of the carbon footprint while advancing towards purely passive optical networks, we have emphasized th...

Power grids are facing new challenges as a consequence of an increase in the use of renewable energy sources (RES). The fluctuation in power supply from these energy sources results in insecure and unstable operating points. Furthermore, the integration of distributed energy resources (DER), as well as distributed information systems, poses serious stability and security challenges in power net...

Abstract – This paper gives a brief overview of production facilities from renewable energy sources which especially influence the power system with variable production. The paper describes some basic ways of connection and technical data relevant for the design of production plants, as well as the most important influences on the power system, especially with respect to the following: voltage,...

Complex power generation scheduling, correlated uncertainties, environmental issues and hybrid energy system modeling have become very important research topics due to rapid growth of large-scale distributed renewable energy system, deregulated electric power markets and responsive demand. The intermittent nature of the primal energy sources (i.e. wind, sun, water) increases uncertainty as well...

The recent growth of renewable energy sources, i.e. wind and solar sources, in electrical power systems is tremendous. Generation from renewable energy sources is mainly added to the power network in a decentralized fashion, and the availability of the generation depends on weather conditions. One of the most common renewable generation techniques is photovoltaic (solar) generation. Regarding t...

At present scenario, renewable energy sources are needed to meet the energy demand. They also mitigate environment pollution problems. The shortage of electrical energy demand can be meeting with renewable energy resources. A wind turbine (WT) and photovoltaic (PV) solar panels are primary energy sources. Grid connected renewable energy source like wind energy and solar energy are used to conne...
