We consider the problem of fair allocation of the cost of a transmission system among load and generation entities using the marginal participation approach. We show that a cost-causal approach involving capacity-based line cost rate and a min-max fair economic slack bus selection for price-taking entities leads to a rigorously fair and more accurate implementation of marginal participation method. In the existing methods the counter-flows are masked, which is a compromise with fairness and linearity. However, if the counter-flows are incentivized then it can lead to pay-offs to some entities. The proposed approach solves the problem of pay-offs without masking the counter-flows. This is achieved by separation of the total transmission services cost into usage, reliability and residual capacity components. The allocation of the first two components is based on the min-max fairness policy, and the residual capacity costs are allocated on a pro-rata basis. Simulation results on multiple IEEE test systems, Indian utility power systems and extensive comparative evaluations for the contemporary methods demonstrate the claims made.

我们考虑使用边际参与法在负荷和发电实体之间公平分配传输系统成本的问题。我们表明，成本为因的方法涉及基于容量的线路成本率和为取价实体选择的最小-最大公平经济闲置巴士，从而导致严格公平，更准确地实施边际参与方法。在现有方法中，逆流被掩盖，这是公平性和线性的折衷方案。但是，如果激励了逆流，则可能导致向某些实体带来收益。所提出的方法解决了回报问题，而没有掩盖逆流。这是通过将传输服务总成本分成使用，可靠性和剩余容量部分来实现的。前两个组成部分的分配基于最小-最大公平性策略，而剩余容量成本则按比例分配。在多个IEEE测试系统，印度公用事业电力系统上的仿真结果以及对现代方法的广泛比较评估证明了所提出的主张。
