基于临界区域投影的多区域经济协调调度

Coordinated Multi-area Economic Dispatch via Critical Region Projection

Ye Guo, Lang Tong, Wenchuan Wu, Boming Zhang, Hongbin Sun

摘要:

提出了一种多区域电力系统协调经济调度方法。该方法以边界相位角为耦合变量,利用了由主动约束和非主动约束定义的局部问题中的临界区域的结构。对于由协调器给出的固定边界状态,局部算子计算包含边界状态的临界区域的系数和最优费用函数的系数,然后将它们传送到协调器,协调器进而优化边界状态以使总成本最小化。该算法通过局部算子和协调器之间的迭代,在有限步内收敛到全局最优解,并且需要有限的信息共享。

英文摘要:

A coordinated economic dispatch method for multi-area power systems is proposed. Choosing boundary phase angles as coupling variables, the proposed method exploits the structure of critical regions in local problems defined by active and inactive constraints. For a fixed boundary state given by the coordinator, local operators compute the coefficients of critical regions containing the boundary state and of the optimal cost functions then communicate them to the coordinator who in turn optimizes the boundary state to minimize the overall cost. By iterating between local operators and the coordinator, the proposed algorithm converges to the global optimal solution in finite steps, and it requires limited information sharing.
