电力市场环境下,各省级电力公司的购电计划中除了一定的固定购电合约以外,在一定的条件下还还存在着自由购电空间。对如何确定省级电网企业的自由购电空间的问题进行研究,提出一套较为完整的判别体系流程,对不同购电情况下的购电量以及购电费用建模分析,并在存在购电优化空间的条件下构建了购电优化模型。通过南方某省电网企业2006年的购电实际数据进行验证分析,结果表明,该购电优化空间判别方法和购电优化模型能够为省级电网企业的购电策略提供可靠合理的辅助决策分析。
In the electricity market environment, except for certain fixed purchase and purchase contracts, the power purchase plans of provincial power companies still have free power purchase space under certain conditions. How to determine the provincial power grid companies free access to electricity space to study the problem, put forward a more complete system of discriminant system, the purchase of electricity under different power purchase and purchase costs modeling and analysis, and in the presence of electricity purchase optimization Space under the conditions of the purchase of electricity optimization model. The results show that the optimization method of purchasing power optimization space and power purchase optimization model can provide reliable and reasonable decision support for power purchase strategy of provincial power grid enterprises.
