摘要: |
需求响应项目的推广以及风电并网后电源侧出力的不确定性,给电力系统的输电网规划带来了新的机遇和挑战。为利用需求响应减少建线投资,建立了考虑直接负荷控制参与N-1预想故障潮流调整的输电网规划模型。采用基于历史数据凸包顶点的极限场景法处理风电不确定性,保证所建立的输电网规划模型为易于求解的混合整数规划问题。结合实际工程参数,基于改进的IEEE24节点系统进行仿真。仿真结果体现了直接负荷控制在缓解潮流越限、减少建线成本方面的作用,说明需求响应措施在保证系统运行安全性的前提下能够提高规划经济性,通过调整凸包范围能够有效调节所提模型的经济性与鲁棒性。 |

Abstract: |
The promotion of demand response programs and the uncertainty caused by wind power integration create opportunity and challenge to transmission network expansion planning. To defer the transmission line investment with demand response, the transmission expansion planning model is proposed considering direct load control in generation re-dispatch for N-1 contingency. The extreme scenario method based on the convex hull vertices of history data is utilized to tackle with wind power uncertainty, which ensures the proposed model is a solvable mixed integer linear programming model. The modified IEEE 24-node system is tested with practical parameters. The function of demand response in relieving power flow overload and reducing transmission line investment is presented in the simulation results, which indicates demand response can improve the economy of power grid planning with the guarantee of system operation security. By adjusting the range of convex hull, the balance between economy and robustness of the proposed model can be reached.
