目前，能源控制中心对燃料成本和机组运行成本的日益关注，使得实际经济调度（艾德）问题的求解方法有了新的进展。艾德的目标是在满足实际约束和负荷需求的情况下调度承诺机组的输出功率。发电机的爬坡率限制、禁止运行区域的非凸性和不连续性、阀点效应的非光滑特性、发电机组的多燃料类型、输电线路损耗以及实际电厂中大量机组的存在使得这一问题很难解决。在这项研究中，一个新的解决方案的方法，结合经典的基于梯度的优化技术和一个新的增强的简化群优化算法，全面提出并成功地应用于确定可行的，强大的，快速和全球或近全球最优解的快速时间框架内的艾德问题。模拟进行了四个测试系统，包括10，15，40和80个单位使用建议的优化技术在Fortran电站4.0软件。目前的建议优于该领域最近最先进的文献中展示的其他方法。
Nowadays, the rising concern about the costs of fuel and operation of generating units in the energy control centre deserve progress of solution methodologies for the practical economic dispatch (ED) problems. ED aims to schedule the committed units' output power while satisfying practical constraints and load demand. The generator ramp rate limits, non-convex and discontinuous nature of prohibited operating zones, non-smooth characteristic of valve-point effects, multi-fuel type of generation units, transmission line losses and the large number of units in practical power plants make this problem very hard to solve. In this study, a new solution method of integrating the classical gradient-based optimisation technique and a new enhanced simplified swarm optimisation algorithm is comprehensively presented and successfully applied to determine the feasible, robust, fast and globally or near-globally optimal solution within a rapid timeframe for the ED problems. The simulations are carried out on four-test systems, including 10-, 15-, 40- and 80-units using the proposed optimisation technique in the Fortran Power Station 4.0 software. The current proposal outperforms other methods showcased in the recent state-of-the art literature in the area.
