Optimized Resource Management for PV–Fuel-Cell-Based Microgrids Using Load Characterizations

Abstract: Maintaining a reliable and cost-effective operation in microgrids has a significant importance. One factor required for optimal operation of the microgrid is to keep a certain energy reserve without unnecessary cost to satisfy load variations. In this paper, an optimal reserve assessment of photovoltaic- and fuel cell-based microgrids is investigated while considering reliability and economic aspects. A typical residential load is predicted to introduce an optimal power sharing approach, and accordingly, to achieve reliable and cost-effective system operation. Load sharing between sources in microgrids affects the cost and also the source’s ability in responding to load variations. A nonlinear frequency droop scheme is then used as a tool to achieve the optimization objectives such that the operating cost is minimized without jeopardizing the microgrid’s ability of responding to sudden load variations. Presented results confirm the validity of the power sharing approach and verify its effectiveness and feasibility.

Options for Near-Term Phaseout of CO2 Emissions from Coal Use in the United States

Abstract: The global climate problem becomes tractable if CO2 emissions from coal use are phased out rapidly and emissions from unconventional fossil fuels (e.g., oil shale and tar sands) are prohibited. This paper outlines technology options for phasing out coal emissions in the United States by ∼2030. We focus on coal for physical and practical reasons and on the U.S. because it is most responsible for accumulated fossil fuel CO2 in the atmosphere today, specifically targeting electricity production, which is the primary use of coal. While we recognize that coal emissions must be phased out globally, we believe U.S. leadership is essential. A major challenge for reducing U.S. emissions is that coal provides the largest proportion of base load power, i.e., power satisfying minimum electricity demand. Because this demand is relatively constant and coal has a high carbon intensity, utility carbon emissions are largely due to coal. The current U.S. electric grid incorporates little renewable power, most of which is n...

Power Electronic Systems for the Grid Integration of Wind Turbines

Abstract: The use of wind power generation is increasingly being pursued as a supplement and an alternative to large conventional central power stations The specification of the power electronics interface is subject to requirements related not only to the renewable energy source itself but also to its effects on power system operation, especially where the intermittent energy source constitutes a significant part of the total system capacity In this paper, current technology and new trends in power electronics for the integration of wind power generators are presented

Allocation of Centralized Energy Storage System and Its Effect on Daily Grid Energy Generation Cost

Abstract: The increasing limitations on available energy require use of new environmentally friendly resources and enhancement of utilization efficiency of available resources. Energy storage systems (ESSs) are a promising technology to realize such a goal; however, their application in networks requires an investment that must be economically justified. This study examined the effect of ESS use on energy generation costs in networks for a specific time period. This includes determining the best location for installation of the ESS and the best possible operation schedules for the ESS and power plants to achieve the greatest decrease in daily energy generation costs. The influences of all the factors affecting the final solution were studied under different scenarios. The effects of power plant cost functions, transmission line capacity, and network upgrades were compared. All scenarios were implemented in an IEEE standard 30-bus network. The best possible specifications of ESS can reduce daily energy generation cost by 3% for selected power plant cost functions. It was found that the use of ESS in a network uniformed stress on the transmission line and, in such a case, it would be possible to defer the network upgrade for 21 years.
