Distributed Generation (DG) in the form of Renewable Power Generation systems is currently preferred for clean power generation. However due to their intermittent and unpredictable nature, energy storage must be used to ensure that the load is met at all times. There are many possible options for energy storage and the most popular and technologically matured option, batteries, is the subject of this...
Energy management of CHP-based microgrid is largely dependent on optimal deployment of distributed energy resources (DERs), where optimal bus-locations, capacity-sizes, and types are three major points to be considered in a microgrid planning. Investment and O&M cost, including fuel cost, are solely dependent on types of DERs. Present paper searches a way-out of how a electrical tracking demand...
Over last two decades the risk and reality of environmental degradation have become more apparent with increasing economic development and population growth. Solving the current environmental problems, while addressing issues related to electricity generation and solid wastes problems, requires long-term potential actions for sustainable development. In this regard, renewable energy resources are...
Generation disruption is associated with poor quality of power as it causes both frequency and voltage reductions and at its severity, hampers reliability of supply to the customers. Improving power quality and reliability (PQR) may become the key benefit of micro-grid if its generation adequacy is properly addressed at the planning stage. Again, higher reliability level requires system reinforcements,...
In the present paper, authors presents a value-based comparative analysis between electrical thermal demand tracking modes of operations at the planning stage from owner's point of view. Worth of operational strategy is evaluated using maximization of net present value (NPV) of 6-bus meshed and 14-bus radial microgrids which are assessed from optimal deployment their DERs with respect to optimal locations,...
California's enactment of a 20% Renewables Portfolio Standard (RPS) by 2010 and an announced policy preference for an increase to 33% by 2020 poses operational and electricity market challenges associated with integrating such high levels of renewable resources into the state's existing transmission system. The output of wind, solar, and ocean generation resources vary according to the availability...
Importance of coal management in power plant is very much significant and also one of the most critical areas in view of plant operation as well as cost involvement, so it forms an important part of the management process in a power plant. It deals with the management of commercial, operational and administrative functions pertaining to estimating coal requirements, selection of coal suppliers, coal...
In recent years, there is a strong trend towards generation of wind power across the globe in geographically suitable areas with a more or less stable wind velocity. However, the erratic nature of wind velocity as a power source is leading to problems of voltage/frequency oscillations and stability in wind energy conversion systems (WECS). Therefore, extensive research is being carried out for efficient...
Microgrids comprise a network of small scale distributed energy resources (DERs) like fuel cells, micro turbines, PV arrays and wind turbine etc. and energy storage devices. Current deregulation regime is encouraging open competition amongst the small/medium utility service providers in providing quality and reliable 'clean' power to the customers at an economic rate. Economic power production is...
