摘要

经济运行域的构建是实现大电网调度自动巡航的第一步。文中将经济运行域定义为各种调度目标偏好下的所有日前安全约束最优发输电计划的集合。针对直流跨区互联大电网，以发电成本最小、碳排放最少和污染物排放最少为目标，构建了一体化多目标日前发输电计划模型。利用法线边界交叉法将该多目标优化问题转化为多个单目标优化问题，进而基于同步型交替方向乘子法构建送、受端电网分解协调模型，实现分布式求解。求解得到分布均匀的Pareto前沿面，即为经济运行域。对由2个IEEE 39节点系统改造的两区域直流互联系统进行仿真，验证了所提方法的有效性。

Abstract

The construction of economic operation region (EOR) is the first step to realize automatic cruise function for bulk power grid dispatching. EOR is defined as the set of all optimal security-constrained day-ahead generation and transmission schedules with various preferences for dispatching objectives. Then

this paper develops a integrated multi-objective model of day-ahead generation and transmission scheduling for inter-regional interconnected bulk power grid via high voltage direct current (HVDC) tie-line

to minimize power generation cost

carbon emission and pollutant emission. The multi-objective optimization problem is transformed into a series of single-objective optimization problems by using the normal boundary intersection (NBI) method. And a decomposition-coordination model for sending and receiving power grids based on synchronous alternating direction method of multipliers (SADMM) is constructed for each single-objective optimization problem to realize distributed solution. Finally

a uniformly distributed Pareto frontier is obtained

which is the EOR. Modified from two IEEE 39-bus systems

a test model of a two-area interconnected system via HVDC tie-line is built. The simulation verifies the effectiveness of the proposed method.
