In value-based transmission planning, market efficiency and associated economic benefits can be achieved from transmission solutions that reduce system congestions. However, to accrue the most value and design the most cost effective transmission solution, it is beneficial to understand the interactions among congested flowgates and strategically address selected congestion issues collectively rather...
In MISO Market Efficiency Planning Study, a critical task is to pick from congested flowgates the ones that have the most potential economic benefits. A new ranking strategy, Estimated Potential Benefit (EPB), is proposed. To compare the performance of the new proposed ranking strategy with commonly used ones, ranking correctness index is introduced as a quantitative measure. EPB not only has the...
Congested flowgate ranking is a process to rank flowgates by the potential benefits associated with each flowgate when it is relieved. The rank can be used to help identify top congested flowgates for full evaluation and planning. Ideally, congested flowgates should be ranked by their potential benefits when congestion is relieved individually. This approach however requires one change case simulation...
New wind power installations in china have doubled every year since 2004. By 2010, Chinas wind generation capacity of 45 GW ranked fi rst in the world. Figure 1 shows how the installed wind capacity in China grew from 20002010. A total of 30 of 31 provinces, municipalities, and autonomous regions have wind farms. (This article does not discuss wind power development in Hong Kong, Macao, and Taiwan...
Quantifying the economic benefit of a transmission upgrade is a critical step in economic transmission planning. Because of the complexity of the energy market, and the difficulties of estimating the FTR revenue and marginal loss credit in the planning horizon year, it is not easy to find an economic index which can accurately capture the economic benefit for all kinds of entities. This paper shows...
