An Offer-Based Approach for Transmission System Capacity and Reactive Power Supply in Restructured Electricity Markets

重组电力市场中输电系统容量和无功电力供应的基于报价的方法joe chow大多数解除管制的电力市场都是基于开放接入的输电系统和能源的位置边际价格。可靠性所需的所有其他要素都被纳入辅助服务。在这样的市场设计中，输电系统仍然受到监管，除非系统可靠性存在问题，否则没有适当的激励措施来促进包括无功功率在内的未来扩张。在本提案中，我们提出了一个根本不同的观点，即输电系统应包括以固定回报率偿还的受管制部分和只有在对系统运行有利时才支付的不受管制部分，例如消除具有约束力的系统可靠性约束和降低总体生产成本。因此，新的输电设施可以根据地区能源价格差异进行补偿。这项研究的动机是基于最近开发的基于报价的实时电力市场动态无功供应方法，包括以固定支付为基础的供应，以确保基本的系统运行，以及仅在必要时才承诺的市场供应。在这项工作中，我们的目标是建立一个统一的方法来传输系统的成本，这将允许当前的做法作为特殊情况。智力优势：目前大多数研究都集中在微调与解除管制市场的各个部门相关的成本分配和市场力量分析上。所提出的方法是新颖的，具有很大的潜力，可以鼓励新的输电投资，以额外转移更便宜的能源，并减少负荷削减的可能性。它还将为大学研究人员、电力市场设计师和能源管理供应商提供新的研究方向。更广泛的影响：拟议的方法将导致更多的输电系统投资，提高电力市场和电力消费的效率。PI计划将研究成果纳入伦斯勒大学的“电力系统运行”课程。PI将继续让少数族裔和代表性不足的学生群体参与研究。

An Offer-Based Approach for Transmission System Capacity andReactive Power Supply in Restructured Electricity MarketsJoe ChowMost deregulated electricity markets are based on an open-access transmission system and locational marginal prices for energy. All other elements required for reliability are folded into ancillary services. In such a market design, the transmission system remains regulated, without proper incentives for future expansion including reactive power, except when system reliability is at issue. In this proposal, we offer a fundamentally different view that the transmission system should consist of a regulated part reimbursed at a fixed rate of return and a de-regulated part paid only if it offers benefits to the system operation, such as removing binding system reliability constraints and reducing the overall production cost. Thus, new transmission facilities can be compensated based on locational energy price differences. The motivation for this research was based on a recently developed offer-based approach to dynamic var supplies in the real-time electricity market, encompassing a fixed-payment-based supply to ensure basic system operation and a market-based supply committed only when necessary. In this work, we aim to establish a unified approach to transmission system costs, which will allow current practices as special cases. Intellectual Merits: Most current research is focused on fine tuning the cost allocation related to various sectors of the deregulated market and on market power analysis. The proposed approach is novel and has a high potential for encouraging new transmission investments for additional transfer of less expensive energy and reduced probability of load curtailment. It will also generate new investigative directions for university researchers, power market designers, and energy management vendors. Broader Impacts: The proposed approach will lead to more transmission system investments and improve the efficiency of power markets and power consumption. The PI plans to include the research results in the "Power System Operation" course taught at Rensselaer. The PI will continue to involve minority and under-represented groups of students in the research.
