Ever increasing concern of environmental safeguard makes renewable energy sources (RES) useful for emission reduction as well as for production cost minimization. In this article, the multiobjective economic emission dispatch (EED) model with security constraints incorporating photovoltaic, nonconvex thermal, and wind units is introduced for hydro-thermal-solar-wind power scheduling arrangement. However, the significant reduction of emission is the foremost perspective for environmental sustainability and penetration of RESs into the electrical grid is being encouraged tremendously. To diminish the power generation expenditure and pollution generated by fossil fuels, renewable solar PV and wind power-oriented hydro-thermal scheduling have significant worth. Existing algorithms do not perform satisfactorily for unpredicted solar and wind-based nonlinear hydro-thermal-wind-solar scheduling problems and it may give local optimal solutions instead of global optimal solution. To overcome the shortcomings of the existing algorithms, an effective, and an intelligent robust algorithm, named moth flame optimization (MFO) has been proposed for solving the said nonlinear optimization problem. This article describes a scientific review on the application of the proposed method to obtain the scheduling of optimal generation for hydrothermal systems by incorporating RESs like solar PV and wind plant. Optimal solutions gained by the employment of different optimization methods for a variety of test instances are demonstrated and the projected methods are compared in terms of attained optimal solutions and convergence speed. The proposed MFO algorithm is competent for potential/hopeful outcomes, and it reduces the electrical power generation cost and emission significantly. The simulation outcomes reveal the usefulness and feasibility of the proposed method.

使用飞蛾火焰优化的太阳能-风-水-热调度

对环境保护的日益关注使得可再生能源 (RES) 对于减排和生产成本最小化非常有用。在本文中，针对水-热-太阳能-风力发电调度安排引入了具有安全约束的多目标经济排放调度 (EED) 模型，该模型结合了光伏、非凸热和风力单元。然而，显着减少排放是环境可持续性的最重要前景，并且正在大力鼓励 RES 渗透到电网中。为了减少化石燃料产生的发电支出和污染，可再生太阳能光伏和以风力发电为导向的水热调度具有重要价值。现有算法不能很好地解决不可预测的太阳能和风能非线性水热风能调度问题，它可能会给出局部最优解而不是全局最优解。为了克服现有算法的不足，提出了一种有效的、智能的鲁棒算法——飞蛾火焰优化(MFO)来解决上述非线性优化问题。本文描述了对所提出方法的应用的科学回顾，该方法通过结合太阳能光伏和风力发电厂等 RES 获得水热系统的最佳发电调度。展示了通过对各种测试实例采用不同的优化方法获得的最优解，并在获得的最优解和收敛速度方面比较了预测方法。所提出的 MFO 算法能够胜任潜在/有希望的结果，并且它显着降低了发电成本和排放。仿真结果揭示了所提方法的实用性和可行性。
