The practices fortheprocurement for the procurement of voltage control capability need changing because of the evolution of the power system driven by the penetration of renewable sources, low carbon policies, and decentralisation. New providers have to be involved. Therefore, new mechanisms to achieve cost-effective solutions have to be encouraged. To this aim, a cost-based incentive mechanism and a weighted auction are proposed for procuring additional reactive power capacity. Both mechanisms are conceived for encouraging effective investment in voltage control by reducing the overall procurement cost. Hence, the voltage sensitivity of the reactive power provider is part of both mechanisms. Voltage sensitivity is evaluated through the Multi Infeed Interaction Factors while the American Electric Power methodology is used for identifying the reactive power costs. The proposed mechanisms are general, and they can be exploited in transmission and distribution networks irrespective of the asset, which provides the reactive capacity. A case study concerning the 39-bus New-England power system is presented for providing the proof of concept of the proposed mechanisms. The analysis of the two mechanisms’ pros and cons highlights that the weighted auction creates competition and shows low risks related to the exercise of potential market power.

无功功率灵活性投资的报酬机制

由于可再生能源渗透、低碳政策和权力下放推动电力系统的发展,电压控制能力的采购实践需要改变。必须涉及新的供应商。因此,必须鼓励实现具有成本效益的解决方案的新机制。为此,提出了一种基于成本的激励机制和加权拍卖,以获取额外的无功容量。这两种机制旨在通过降低总体采购成本来鼓励对电压控制的有效投资。因此,无功功率提供器的电压灵敏度是这两种机制的一部分。电压灵敏度通过多馈电交互因素进行评估,而美国电力方法则用于确定无功功率成本。所提出的机制是通用的,它们可以在输配电网络中使用,而与提供无功容量的资产无关。提出了一个关于 39 总线新英格兰电力系统的案例研究,以提供所提议机制的概念证明。对两种机制优缺点的分析表明,加权拍卖创造了竞争,并显示出与行使潜在市场力量相关的低风险。提出了一个关于 39 总线新英格兰电力系统的案例研究,以提供所提议机制的概念证明。对两种机制优缺点的分析表明,加权拍卖创造了竞争,并显示出与行使潜在市场力量相关的低风险。提出了一个关于 39 总线新英格兰电力系统的案例研究,以提供所提议机制的概念证明。对两种机制优缺点的分析表明,加权拍卖创造了竞争,并显示出与行使潜在市场力量相关的低风险。
