Framework for Value Based Constraint Reliability in a Restructured Environmnet

在现代电力系统中，可靠性评估和控制方案的选择对于解决新参与者的不确定性和演变具有重要意义。因此，先进的计算工具将为分析竞争效用提供一个框架，这将是研究的挑战之一。通常，对大型基础设施的分析带有不确定性，例如可能影响系统充分性的不稳定现象或突发事件。因此，需要具有实时计算能力、不确定性下的决策、评估新范式下的充分性、可靠性和稳定性的创新工具。该提案的研究部分集中在能源部和IEEE可靠性和系统经济学工作组早先确定的优先主题上。提出的集成方案为开发基于值的可靠性控制方案提供了框架，该方案采用稳定裕度来定义以可用传输能力（ATC）为约束的新可靠性指标。这些新指标将在输电能力评估和基于值的输电可靠性评估中计算。同时，提出了一种多目标优化方案，以实现可靠性和稳定性的最优权衡。此外，还将对分布式电力环境进行可行性、成本效益分析和分配策略。拟议的方案将在一个小型基准测试平台上进行测试，然后是一个工业规模的系统。研究结果将会全面公布，业界的意见亦会被接纳，以加强这项多年计划。

In the modern power system, reliability assessment and selection of control options will be important to address the uncertainties and evolution of new players. Therefore advance computational tools that will provide a framework for analysis of competitive utility will be one of the research challenges. Typically, the analysis of large-scale infrastructures carries uncertainties such as instability phenomenon or contingencies that may affect system adequacy. Therefore, innovative tools, which feature real-time computational capabilities, decision-making under uncertainty, assessing adequacy, reliability, and stability under new paradigms are needed.The research component of this proposal is focused on the priority topics earlier identified by DOE and IEEE Working Group on Reliability and System Economics. The Proposed integrated scheme sets the framework for developing a value-based reliability control scheme, which incorporates Stability Margins to define new reliability indices with Available Transfer Capability (ATC) as constraints. These new indices will be computed in the assessment of transmission capability and value-based transmission reliability. Also, a multi-objective optimization scheme is proposed to achieve optimum trade-off between reliability, and stability. In addition the feasibility Cost Benefit Analysis and allocation strategy for a distributed power utility environment will be performed.The proposed scheme will be tested using a small benchmark testbed followed by an industry-sized system. Research results will be fully disseminated and industry feedback will be accommodated in enhancing this multi-year project.
