A microgrid is a cluster of interconnected distributed generators, loads and intermediate storage units that cooperate with each other to be collectively treated by the grid as a controllable load or generator. Power quality events and pre-set conditions will make the microgrid disconnect from the main grid and operate as a separate island. This paper enumerates and discusses the issues concern...

This paper proposes a Multi-Code Multi-Carrier CDMA, best suited for multi-rate services using multicode schemes and multi-carrier services used for high rate transmission as required for the Universal Telecommunication Mobile Systems (UMTS) Long Term Evolution (LTE). The system performance has been analyzed and evaluated by means of signal-to-noise plus interference ratio and bit error rate un...

Two of the most important technologies for future power systems to reduce greenhouse gas are electric vehicles (EVs) and renewable generation. When EVs become more common, the overall demand of electricity will significantly increase because EVs consume a large amount of electricity. Also, a daily load curve with EVs heavily depends on how much electricity EVs consume and when electricity is co...

In this paper we demonstrate the contribution of information systems towards a sustainable and reliable power supply. Following a Design Science approach we develop an information system for microgrid operation at a U.S. army base. Microgrids enable an improved integration of distributed renewable energy sources and increase the robustness of the overall power grid. The microgrid in this study ...

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...

This paper proposes a fast strategy for optimal dispatching of power flows in a microgrid with storage. The investigated approach is based on the use of standard Linear Programming (LP) algorithm in association with a coarse linear model of the microgrid. The resulting computational time is compatible with simulations over long periods of time allowing the integration of seasonal and stochastic...

The electricity sector in India had an installed capacity of 233.929 GW as of December 2013. India currently suffers from a major shortage of electricity generation capacity, even though it is the world's fourth largest energy consumer after United States, China and Russia. The utilization of renewable energy sources such as solar power, wind power, biomass power etc. play a dominant role in el...

Abstract In order to further promote the new energy consumption of combined cooling, heating, and power (CCHP) microgrid, reduce carbon emissions, optimize total operating cost a low-carbon optimal scheduling model CCHP microgrid was proposed. It considered demand response (DR) shared storage (SES). Firstly, concept SES its operation mode are applied microgrid. Secondly, in take advantage flexi...

By constructing a DC multi-microgrid system (MMGS) including renewable energy sources (RESs) and electric vehicles (EVs) to coordinate with the distribution network, utilization rate of RESs can be effectively improved carbon emissions reduced. To improve economy MMGS reduce network loss cooperative double-loop optimization strategy is proposed. The inner-loop economic dispatching reduces daily...
