| 摘要: |
| 为了适应区域间的电能交易量逐步增加这一趋势,建立了互联电力合同参数优化模型。该模型由联网调度模型和合作对策模型2个子模型组成。联网调度模型用于确定最优互联合同交易电量,合作对策模型用于确定最优合同交易价格。联网调度模型以古诺模型为基础,以社会福利最大化为目标,在考虑了网络约束的影响下,通过引入一阶优化条件将其转化为线性互补问题(LCP)加以求解。合作对策模型采用了Shapley值分配各联网成员间的效益。并以IEEE30-bus系统为背景,构造了电力市场算例,通过模型的仿真计算表明了模型的合理性和算法的有效性。 |

| Abstract: |
| To meet the needs of increasing energy interchanges between power grids,an optimization model is constructed for interchange contract parameters,which is comprised of two sub-models,i.e.interchange scheduling model for amount and cooperative game model for price.The interchange scheduling model is based on Cournot model,aiming at the maximized social welfare with grid constraints,and its solution is obtained by introducing the first order optimality conditions to formulate it as a LCP(Linear Complementary Problem).The cooperative game model adopts Shapley value to distribute the benefit among the interconnected power grids.Taking IEEE 30-bus system as its background,a power market is built and the simulative calculations have verified the rationality of the model and the effectiveness of the algorithm. |
