The optimal generation for short-term hydrothermal scheduling (OGStHS) with the deliberation of various purposes is a complex non-linear constrained optimization problem. There exist numerous constraints, which make the OGStHS optimization problem more complicated. The considered constraints for this problem are mostly related to energy performance, operational conditions, water, and power infrastructure. All these constraints would generally influence the cost of fuel. In this study, a multi-objective optimization form of OGStHS is suggested to estimate the minimum cost of fuel, which mainly influences industrial operation. The water transfer delays among multi-related reservoirs and the thermal plants’ valve-point influences are considered for the accurate formulation of the OGStHS problem. Meantime, a grasshopper optimization algorithm (GOA) is performed to handle the OGStHS problem by getting optimized for both objectives concurrently. A modern approach is shown in this study to get a solution to the OGStHS problem. Furthermore, to deal with the complex restraints efficiently, modern heuristic restriction treatment processes with no drawback impact frames have been offered in this study. Two hydrothermal power systems have illustrated the suggested GOA technique’s utility and performance. Compared with other available approaches, the analytical results are admitted that GOA can provide a better understanding by decreasing fuel cost and emission concurrently.

短期热液最优调度的蝗虫优化算法

考虑各种目的的短期热液调度优化生成（OGStHS）是一个复杂的非线性约束优化问题。存在众多的约束条件，这使得OGStHS优化问题变得更加复杂。该问题所考虑的限制主要与能源性能、运行条件、水和电力基础设施有关。所有这些限制通常都会影响燃料成本。在本研究中，提出了 OGStHS 的多目标优化形式来估计主要影响工业运行的燃料的最小成本。为了准确制定 OGStHS 问题，考虑了多相关水库之间的输水延迟和热电厂阀门点的影响。同时，执行 Grasshopper 优化算法 (GOA)，通过同时针对两个目标进行优化来处理 OGStHS 问题。本研究展示了一种现代方法来解决 OGStHS 问题。此外，为了有效地处理复杂的约束，本研究提供了没有缺陷影响框架的现代启发式限制处理过程。两个水热发电系统说明了所建议的 GOA 技术的实用性和性能。与其他可用方法相比，分析结果表明 GOA 可以通过同时降低燃料成本和排放来提供更好的理解。
