Abstract As the worldwide use of wind turbine generators in utility-scale applications continues to increase, it will become increasingly important to assess the economic and reliability impact of these intermittent resources. Although the utility industry appears to be moving towards a restructured environment, basic economic and reliability issues will continue to be relevant to companies involved with electricity generation. This paper is the second in a two-part series that addresses modeling approaches and results that were obtained in several case studies and research projects at the National Renewable Energy Laboratory (NREL). This second paper focuses on wind plant capacity credit as measured with power system reliability indices. Reliability-based methods of measuring capacity credit are compared with wind plant capacity factor. The relationship between capacity-credit and accurate wind forecasting is also explored.

Measuring Wind Plant Capacity Value
Electric utility planners and wind energy researchers pose a common question: What is the capacity value of a wind plant? Tentative answers, which can be phrased in a variety of ways, are based on widely varying definitions and methods of calculation. From the utility's point of view, a resource that has no capacity value also has a reduced economic value. Utility planners must be able to quant...
متن کاملAlternative renewable energy scenarios for New York
This case study compares the cost of maintaining a proposed subsidy for New York’s three upstate nuclear power plants (Fitzpatrick, Nine Mile Point Unit 1, and Ginna) with the cost of replacing the plants with renewable technologies over the time period from 2016 to 2050. Three alternative renewable scenarios are compared with two nuclear scenarios in terms of overall system costs, which compri...
متن کاملMulti Objective Scheduling of Utility-scale Energy Storages and Demand Response Programs Portfolio for Grid Integration of Wind Power
Increasing the penetration of variable wind generation in power systems has created some new challenges in the power system operation. In such a situation, the inclusion of flexible resources which have the potential of facilitating wind power integration is necessary. Demand response (DR) programs and emerging utility-scale energy storages (ESs) are known as two powerful flexible tools that ca...
متن کاملAn Enumerated Probabilistic Simulation Technique and Case Study: Integrating Wind Power into Utility Production Cost Models
Production cost, generation expansion, and reliability models are used extensively by utilities in the planning process. However, many of these models do not provide adequate means for representing the full range of potential variation in wind power plants. In order to properly account for expected variation in windgenerated electricity in these models, we describe an enumerated probabilistic a...
