TL;DR: In this article, an expression for the additional cost that intermittent generation imposes on a system that is attributable to its intermittent nature is identified, and it is shown that this expression can be reconciled with approaches that look at intermittent renewables on a stand-alone basis and factor in the additional costs of'standby' capacity.
Abstract: There have been attempts, using various approaches, to assess the additional cost of running an electricity system when intermittent renewable generation is used to provide a significant proportion of the energy. The key issues are the difference, in statistical terms, between the resource availability of the intermittent source and conventional generation and the contribution the intermittent source can make to meet the system peak demand while maintaining system reliability. There is considerable agreement over the capacity credits that can be attributed to renewable energy sources, that is the amount of conventional capacity that renewables can reliably displace, yet the implications for costs have proved more controversial. Approaches to calculate changes in overall system cost are examined and an expression for the additional cost that intermittent generation imposes on a system that is attributable to its intermittent nature is identified. Further, it is shown that this expression can be reconciled with approaches that look at intermittent renewables on a stand-alone basis and factor in the additional costs of 'standby' capacity. It is shown that the main source of divergence between estimates of the cost of intermittency is the load factor implicitly assumed for the conventional plant used as a reference. There is only one consistent way to impute the costs of intermittency when the unit cost of intermittent plant is being compared with that of baseload generation plant.

TL;DR: In this paper, a device is disclosed that collects data on renewable power production, meteorological and other information, forecasts short timescale renewable energy production then mitigates costs incurred by power fluctuations by modulating the power output, while maximizing power production revenue.
Abstract: A renewable energy generator imposes costs on a power grid from rapid fluctuations in output. A device is disclosed that collects data on renewable power production, meteorological and other information, forecasts short timescale renewable power production then mitigates costs incurred by power fluctuations by modulating the power output, while maximizing power production revenue. Mitigation may be effected by an AC/DC inverter, an energy storage system, demand response or a FACTS device. The magnitude and costs for modulating response required from energy storage, FACTS or other power modulation equipment is thereby reduced.

TL;DR: The emissions model incorporates the effects of both cycling and start-ups of thermal power plants in analyzing emissions from an electric power system with increasing levels of wind power and concludes that as the wind power penetration increases, pollutant emissions decrease overall due to the replacement of fossil fuels.
Abstract: This paper discusses the environmental effects of incorporating wind energy into the electric power system. We present a detailed emissions analysis based on comprehensive modeling of power system operations with unit commitment and economic dispatch for different wind penetration levels. First, by minimizing cost, the unit commitment model decides which thermal power plants will be utilized based on a wind power forecast, and then, the economic dispatch model dictates the level of production for each unit as a function of the realized wind power generation. Finally, knowing the power production from each power plant, the emissions are calculated. The emissions model incorporates the effects of both cycling and start-ups of thermal power plants in analyzing emissions from an electric power system with increasing levels of wind power. Our results for the power system in the state of Illinois show significant emissions effects from increased cycling and particularly start-ups of thermal power plants. However, we conclude that as the wind power penetration increases, pollutant emissions decrease overall due to the replacement of fossil fuels.

TL;DR: In this paper, a power delivery rate from a renewable power source to a load is managed by determining, by processing circuitry, whether the change in the power generation rate exceeds a limit, and then, adjusting, by control circuitry, a power transfer rate to or from a power storage device, such that the adjusting is sufficient to prevent the power delivery ratio from exceeding the limit.
