基于交替方向乘子法的源网协同多适应规划

电源规划与电网规划紧密相关,有必要考虑其相互影响进行协同规划。该文兼顾分布式决策环境与多适应性条件,提出了一种电源与电网协同的多适应规划框架,利用交替方向乘子法(alternating direction method of multipliers,ADM M)分别构建了耦合共享变量的电源规划决策子问题与电网规划决策子问题,2个子问题相互通信、交替求解,实现了电源与网架协同的分布式自治规划。该框架和方法保留了决策主体信息的私密性,同时确保了电源规划方案和电网规划方案所构成的整体系统的经济性和适应性。在Garver-6系统上对该文方法的有效性进行了验证。

Synergistic Adaptive Planning of Generation and Transmission Using ADMM

Generation and transmission expansion planning interact with each other tightly, it is necessary to take the interaction into account when making planning. This paper proposes an adaptability planning framework of generation and transmission network by taking distributed decision environment and adaptability condition into consideration, and uses alternating direction method of multipliers ( ADMM) to separately construct the decision-making sub-problems of generation planning and network planning with shared variable coupling. The two sub-problems communicate with each other and solve alternatively, which can realize the distributed synergy between generation and transmission network. The framework and approach keep information privacy and remain the economy and adaptability of the whole power system consisting of generation planning and network planning. Case studies based on the Garver-6 power system demonstrates the effectiveness and feasibility of the proposed approach.
