基于潮流追踪和广义发电分配因子的输电费用分摊方法研究

合理分摊输电费用是电网公司、用户和资源优化配置的需要。利用成本加收益方法确定输电费用,并借鉴优势潮流的思想将其分为使用费用和安全费用。使用费用由全体用户承担,潮流追踪法确定的分摊系数均为正值,故使用费用按照潮流追踪法分摊。安全费用仅由正向潮流用户分摊,利用广义发电分配因子法确定用户是否为正向潮流用户,从而决定其是否参与安全费用分摊。方法既保证电网公司的财务平衡,又为负向潮流用户提供激励。利用5节点系统验证了方法的有效性。

Research on Allocation of Transmission Cost Based on Power Flow Tracing and Generalized Generation Distribution Factors

The reasonable allocation of transmission cost is the need of power grid corporation, of the users, also of the optimal allocation of resources. The transmission costs are first calculated by cost plus profit method and then divided into usage costs and security costs learning from the idea of advantage flow method. Undertaken by all users, usage costs are allocated by power flow tracing method, the apportionment factor who determines is always positive. Security costs are assessed only by the users to provide a positive flow. Determined by generalized generation distribution factors (GGDF) method, the positive flow users will be involved in security cost-sharing depended on the distribution factors determined by GGDF, or not to participate in the security cost-sharing. This method can both ensure the financial balance of the grid company and provide an incentive for the negative flow users. At last paper uses a 5-bus system to verify the effectiveness of this method.
