Maria de Lujan Latorre, Gerson C. Oliveira, Ricardo C. Perez, Lucas Okamura, Silvio Binato

摘要:

在本文中,一个综合的和分层的发电和输电扩展规划方法之间的差异进行了描述。然后,详细描述了分层方法。在通项中,投资决策是分步进行的,而不是一个整体优化方案。本文提出了一种随机分层的发输电规划方法的基础上的三个步骤,如下:1。在这一步中,一个综合的扩展规划问题的发电和区域间互联的解决; 2。考虑到(发电和互连)的最优扩展计划,在不监测电路流量限制的情况下(除了互连中的那些,其被监测)执行具有详细网络表示的生产成本模拟;该模拟产生一组最优调度方案(总线负载和发电的向量); 3.然后,应用输电扩展规划(TEP)模型来确定相对于步骤2的所有操作场景鲁棒的最小成本输电扩展规划,使用增强的Benders分解方案:(a)将操作场景的子集并入投资模块中;以及(b)利用产生(好的)可行解和可行性切割的初始集合的“贪婪”算法来呈现“预热”步骤。分层规划方案的应用说明了一个现实的多国发电和输电规划的中美洲电力市场的案例研究。

英文摘要:

In this paper, the differences between an integrated and hierarchical generation and transmission expansion planning approaches are first described. Then, the hierarchical approach is described in detail. In general terms, in this scheme the investment decisions are made in steps, instead of an overall optimization scheme. This paper proposes a stochastic hierarchical generation-transmission expansion planning methodology based on a three-step procedure, as follows: 1. In this step, an integrated expansion planning problem of generation and interregional interconnections is solved; 2. Taking the optimal expansion plan of (generation and interconnections) into account, a production costing simulation with the detailed network representation is performed without monitoring circuit flow limits (except the ones in the interconnections, which are monitored); this simulation produces a set of optimal dispatch scenarios (vectors of bus loads and generation); 3. A Transmission Expansion Planning (TEP) model is then applied to determine the least-cost transmission expansion plan that is robust with respect to all operation scenarios of step 2, using an enhanced Benders decomposition scheme that: (a) incorporates a subset of the operation scenarios in the investment module; and (b) presents a "warm-up" step with a "greedy" algorithm that produces a (good) feasible solution and an initial set of feasibility cuts. The application of the hierarchical planning scheme is illustrated with a realistic multi-country generation and transmission planning case study of the Central America's electricity market.
