Increasing threats of global warming and climate changes call for an energy-efficient and sustainable design of future wireless communication systems. To this end, a novel two-scale stochastic control framework is put forth for smartgrid powered coordinated multi-point (CoMP) systems. Taking into account renewable energy sources (RES), dynamic pricing, two-way energy trading facilities and impe...

The intelligent energy management system is operated automatically to ON and OFF the generating sources as per the load demand. The renewable energy sources used in this energy management system are solar, wind, fuel cell and energy storage element battery as an input source. These renewable energy sources are integrated into the main dc bus through dc-ac converter. Microgrid is basically a gro...

There is increasing demand for the use of alternative renewable energy sources to achieve clean and low-cost electric energy for loads. Wind and solar energies are some of the renewable energy sources which are mostly available in the world. In this study, a hybrid power station has been designed using solar and wind energies.

Creation of an internal market for renewable electricity will involve a political negotiation process, similar to previous EU greenhouse gas negotiations. The Energy Ministers in the EU have agreed on an overall target of 22% of electricity supply from Renewable Energy Sources (RESE) and a distribution of targets over the individual Member States. The REBUS project provides insights in the effe...

• This counterintuitive finding reflects two key characteristics about energy markets: the worldwide increase in renewable energy sources whose output is intermittent and variable; and greater market liberalization, which has made the spot pricing of electricity more volatile. The intermittency of renewable energy sources requires backup generation, typically from generators using fossil fuels....

Due to the increasing penetration of Distributed Generation (DG) technologies, such as photovoltaics, wind turbines, μCHP, biomass, etc., energy production changes from centralized units to diverse distributed units, located at lower voltage levels. In addition, installations of renewable energy resources are promoted by receiving a fixed feed-in tariff. These trends provide new opportunities f...

This paper proposes a novel control strategy in which Renewable Energy Sources (RES) considered new Dynamic Virtual Power Plant (DVPP) concept directly participate to Secondary Frequency Control (SFC). allows full participation of these generators SFC, i.e., the same manner as classic synchronous by fulfilling identical specifications from both and contractual points view. An internal real-time...

Voltage-type sources have dominated as an input source for power electronics converters for a long type. The existence of duality implies that there are also current-type sources. The growing application of renewable energy sources such as wind and solar energy has evidently shown that the current-type input sources exist in reality such as photovoltaic (PV) generator or the feedback technique ...

The expansion of renewable energies is progressing strongly. The influence on the power supply networks by the variability of the infeed must be met with new concepts. In this paper, we investigate the possibilities of integrating microgrids as a cooperating unit in the power supply network to support further expansion of renewable energy sources (RES) power plants. In this paper, a differentia...
