一种区域电力市场多运营主体输电收入分配方法

Transmission income distribution for multiple operators in regional integrated market

随着全国统一电力市场体系的建设,区域电力市场融合发展逐渐加速,跨省区电力直接交易规模不断扩大,跨省区输电费用能否公平、合理分摊也影响着整体区域市场的资源优化和交易积极性。基于现有输配电价核价和收费机制,研究提出一种区域电力市场内多个省级输电网运营主体的输电收入分配方法。以区域内多运营主体联合运营的整体输电网输电损耗最小为目标函数,求解形成跨区域交易合同的最优输电路径,按照各运营主体线路资产利用程度对固定的输电收入进行分摊。通过输电收入的合理分配,扩大区域市场交易规模,促进区域市场中的输电网运营主体资源优化配置,最后采用IEEE30节点系统算例验证了方法的有效性。

With the construction of the unified power market system,the integrated development of regional power markets has gradually accelerated,and the scale of the electricity trade across provinces and regions has been continuously expanded.A transmission income distribution method for multiple transmission network operators in regional integrated market based on the existing transmission and distribution price verification and charging mechanism is proposed.The transmission paths of electricity trade contracts across provinces and regions are optimized with the minimum network loss as the objective function,and the fixed transmission income is allocated according to the utilization of transmission network operator assets.Through the rational distribution of transmission income,the electricity trade scale of the regional market is expanded,which promotes the optimal allocation of transmission resources in the regional market.Finally,the effectiveness of the method is verified by an example of IEEE-30 node system.
