基于机会约束的区域能源互联网优化运行

为保证区域能源互联网的可靠、经济运行，基于机会约束理论对不确定环境下的优化运行方法展开研究。考虑风电出力预测误差随机变量，建立燃气轮机备用容量机会约束条件、备用偏差风险成本目标函数，进而提出一种考虑备用容量的区域能源互联网随机优化运行方法。仿真结果表明所提方法能够有效管控风电并网带来的运行风险，在提高系统运行可靠性的同时，兼顾系统运行和燃气轮机备用的经济性。

Chance-Constrained-Based Optimal Operation for Regional Energy Internet

To ensure reliable and economic operation of regional energy Internet, based on chance constraint theory the optimal operation method under uncertain environment was researched. Considering stochastic variables in wind power output forecasting error, the reserve capacity chance constraint condition for gas turbine and the objective function of reserve deviation risk cost were established, and then, a stochastic optimization operation method of regional energy Internet considering reserve capacity was proposed. Simulation results show that the proposed method can effectively control the operation risks caused by wind power integration, improve the reliability of system operation, and ensure the economy of system operation and gas turbine reservation.
