Abstract

Optimal operation of hydrothermal systems is very complex because it corresponds to a multiperiod, stochastic, large scale and characterized by a nonseparable objective function optimization problem. As a result it is traditionally carried out without taking into account transmission constraints or considering them in a very simplified way. This approach is not adequate to address certain kind of problems such as cost-benefit studies of transmission interconnections in hydro systems or the study of spatial distributions of spot prices ("zones" identification) through the electric network, due to hydro and power flow constraints. In this paper we address the problem of stochastic optimization of large scale transmission constrained hydrothermal systems with applications to the Brazilian case.
竞争框架下输电约束和大型热液系统的随机优化
热液系统的优化运行是一个多周期、随机、大规模、不可分离的目标函数优化问题,是一个非常复杂的问题。因此,在传统上,它是在不考虑传播限制或以非常简化的方式考虑它们的情况下进行的。由于水力和电力流量的限制,这种方法不足以解决某些问题,例如对水电系统中输电互连的成本效益研究或通过电网研究现货价格的空间分布(“区域”识别)。本文以巴西为例,研究了大规模输电约束热液系统的随机优化问题。
