Fossil fuel is considered to be the primary power generation source. As this source is not that eco- and environmentally friendly, researchers are constantly searching for an alternative source for power generation. Renewable energy has drawn much attention in this regard in recent times. For solving economic load dispatch issues, numerous operational constraints must be considered. Due to the restructuring of the power sector, there is competition between different power systems organizations. Increasing fossil fuel costs drive power-producing utilities to adopt a cost-effective technique for dispatching actual power output. Due to the presence of nonlinearity and non-convexity in the fuel of cost function of generators, the economic load dispatch is often considered a complex optimization problem. Many researchers have been optimizing fuel costs to solve the economic power dispatch problem. This paper offers a critical analysis of ELD that takes into account both traditional and non-traditional energy sources. The review covers a variety of algorithms, including hybrid algorithms for integrating renewable energy sources (RES). The paper also focuses on several restricted optimization techniques and contemporary algorithms including PSO, Jaya, GWO, SMO, TLBO, Rao, MRao-2, and MFO to reduce the fuel cost of generation units using large-scale solar PV. Moreover, this paper provides a comprehensive overview of the current state of economic load dispatch and provides valuable insights for electricity researchers and practitioners. It also discusses future technologies and next steps in the field of ELD, emphasizing the need for more environmentally friendly and cost-effective power generation and distribution solutions. Overall, the paper demonstrates the benefits of renewable energy sources as well as optimization techniques for creating a more sustainable and efficient power generation system.

In present scenario, forecasting electricity load, price, wind farm power & solar PV power etc. accurately plays important role while any decision making for planning, operation, and control for the economic & efficient operation of the power system. An Economic Load Dispatch Operation is required for economic & efficient operation of the power plant. It is a used for scheduling the output of the connected generating unit of a plant to fulfil the electricity load requirement at minimum cost by satisfying all inequality and equality constraints. In this paper, firstly 24 hour ahead electricity load has been forecasted on hourly basis. Secondly, this forecasted load is used for predicting day-ahead economic load dispatch operation by using particle swarm optimization. The results show the optimum operating cost.

“…En cuanto al desarrollo tecnológico de generación de las energías renovables destaca la energía eólica. A nivel mundial en el año 2019 la capacidad de generación con energía eólica instalada fue alrededor de 650GW (Sun et al, 2020). Sin embargo, como se mencionó anteriormente uno de sus inconvenientes es la intermitencia en cuanto a la generación, debido a la dificultad en la predicción de la disponibilidad de los recursos naturales.…”

“…Es así que los modelos de DE son clave, ya que analizan las condiciones operacionales del sistema para presentar una propuesta de los sistemas de generación y poder solventar la demanda necesaria en un instante dado, tomando en cuenta aquellos que presentan un bajo costo operacional para proveer el suministro eléctrico, lo que facilita la toma de decisiones. Claro que la generación necesaria en función de la demanda no es la única solución para elevar la eficiencia del sistema, también se pueden implementar medidas para reducir la demanda, aplanando la curva de consumo, reduciendo el consumo en horas punta: utilizando técnicas de mercadeo de energía, aplicando discriminación horaria; campañas para mejorar los hábitos de consumo de los usuarios; instalar equipos como medidores inteligentes que permitan conocer el consumo de los usuarios en tiempo real, gestionándolo de manera bidireccional; reemplazando elementos antiguos con tecnología actual más eficiente, entre otras (Sun et al, 2020;Sovacool, 2009).…”

El modelo de programación lineal de operación (PLO) considera desde el suministro de energía hasta los consumidores finales. Al resolver el PLO de un sistema eléctrico de potencia (SEP), el objetivo es encontrar la asignación óptima o despacho económico (DE) de la potencia de salida entre las tecnologías de generación convencional y la generación de energía renovable (específicamente la eólica) para cubrir carga del sistema a un mínimo costo operacional. En el modelo propuesto se ha empleado un enfoque determinista-lineal con relaciones matemáticas que utilizan variables como: estado de operación de la unidad de generación en función del tiempo, despacho de potencia de centrales eólicas y convencionales, déficit eléctrico, transferencia de potencia entre las barras, pérdidas en las líneas de transmisión. Adicionalmente, se incluyen factores y ecuaciones matemáticas para enfrentar la variabilidad del viento. Se presenta un caso de estudio didáctico para explicar la estructura propuesta.
