摘要

本文给出了水电系统长期热液发电调度的一般组合表示。一般的表示是基于非线性水库运行规则对水电系统的聚合。建立了一种基于确定性热液调度模型求解的有效规则确定程序。为了评估水力发电的改善，将非线性水库运行规则的复合表示与巴西东南电力系统不同规模水力发电系统(最多29个水电站)的传统线性表示进行了比较。结果表明，水力发电有明显改善。

General composite representation of hydroelectric systems

This paper presents a general composite representation of hydroelectric power systems for long-term hydrothermal generation scheduling. The general representation is based on the aggregation of the hydro system through nonlinear reservoir operational rules. A procedure for determining effective rules based on the solution of a deterministic hydrothermal scheduling model is established. In order to evaluate the improvement in hydro generation, the composite representation with nonlinear reservoir operational rules is compared to the traditional linear one for hydroelectric systems with different dimensions (up to 29 hydro plants) taken from the Brazilian southeast power system. The results show a significant improvement in hydro generation.
