“…Las baterías electroquímicas presentan desventajas, tales como: al finalizar su vida útil y al no poseer una infraestructura adecuada de reciclaje contamina el medioambiente [4], su vida útil depende del ambiente de trabajo y del número de cargas/descargas y, lo más importante, no pueden cargarse ni descargarse rápidamente debido a que poseen una resistencia interna grande [5]. Debido a ello queda como resultado la utilización de los volantes de inercia que presentan las siguientes ventajas: tienen un mayor ciclo de cargas/descargas con potencia media a alta (kW a MW) durante cortos periodos (segundos) sin afectar su vida útil [6], alta capacidad de respuesta, es amigable con el ambiente pues no requiere de reacciones químicas, no necesita de condiciones geográficas especiales para su construcción [7]. El principal competidor en términos comparativos que tienen los volantes de inercia son los supercondensadores, los cuales de igual manera presentan las siguientes ventajas sobre las baterías electroquímicas: pueden cargarse/descargarse en períodos cortos (segundos), pueden proporcionar corrientes de cargas altas, poseen un ciclo de vida del orden de millones de veces, trabajan en condiciones de temperaturas muy duras, no poseen en su estructura elementos tóxicos [2].…”

Este artículo presenta el diseño de un sistema de energía basado en volante de inercia para mitigar los huecos de tensión. Con el sistema se mejora la calidad de energía en un punto de una red de distribución, el cual está expuesto a la conexión aleatoria de máquinas eléctricas. Para ello, se modela el sistema de distribución de energía, el sistema de inyección de energía que está compuesto por una máquina eléctrica con volante de inercia, el sistema de conversión de energía bidireccional y el sistema de control de corriente, voltaje y velocidad. El sistema diseñado permite inyectar una potencia de 22.8 kW y capacidad de 1.2 Wh, compensando los transitorios producidos por las cargas conectadas a la red

“…They can be mechanical, magnetic or hybrid. Active and/or passive magnetic bearings are usually employed to hold the flywheel during operation, ensuring a long life, reduced losses and low maintenance [25]. The high-temperature superconducting (HTS) type has also been proposed to levitate and rotate the flywheel [26].…”

Flywheel energy storage is considered in this paper for grid integration of renewable energy sources due to its inherent advantages of fast response, long cycle life and flexibility in providing ancillary services to the grid, such as frequency regulation, voltage support, etc. The fundamentals of the technology and recent developments are reviewed, firstly with an emphasis on the design considerations and performance metrics. Then the progress and development trends in electric motor/generators employed in flywheel energy storage systems (FESS) are summarized, showing the potential of axial-flux permanent-magnet (AFPM) machines in such applications. Design examples of high-speed AFPM machines are provided and evaluated in terms of specific power, efficiency, and open-circuit losses in order to validate their suitability in FESS.

“…Next, the researchers worked on load balancing using energy storage systems like super-capacitors, flywheel, superconducting magnetic energy, pumped storage hydroelectricity (PSH), batteries, and CAES. In [12], the flywheel has been proposed for balancing the load demand but did not consider the optimal dispatch of generator and flywheel. In contrast, electric PSH and boilers for heat [13] and PV forecasts and PSH [14] have been used to enable PV generations in smart grid and increase renewable source penetration but did not consider duck curve situations.…”

The high requirement for electrical energy, Photovoltaic (PV) installation price and environmental issues have led to PV installations' recent worldwide growth. The large PV penetration changes the daily load demands curve, especially on a sunny day, making a massive gap between load demands in the day and the night. This load demand curve shapes the duck curve both in the generation and the load demand side. In a duck curve, thermal generators' fuel costs and emissions are increased because their operation is not optimal, decreasing efficiency. In this study, compressed air energy storage (CAES) is added to the system for load demand balancing. The optimal dynamic economic emission dispatch (DEED) is performed to determine the best pattern of CAES operation and the optimal output of thermal generators to satisfy the 24-hour load demand for minimizing the fuel costs and emissions of the thermal generators simultaneously. The quadratic constrained programming is applied in this paper as the optimization tool for the DEED problem, and it is determined by using the CPLEX solver. Furthermore, the proposed model's feasibility is illustrated using different cases based on the IEEE 30-bus system. As a result, according to the comprehensive operational flexibility analyses, the proposed system is capable to handles the fast ramp of the duck curve, proved by no flexibility deficit in the planning periods. Finally, the thermal generators' fuel costs and emissions are also minimized.
