“…Our control strategies are based on distributed fast-response energy storage systems, which grant a positive motivation for the development of distributed renewable energy. Comparing to other works, [21][22][23] our control strategies can not only prevent a blackout from happening but also greatly decrease the requirement of backup power from generators to restore normal functioning of the power systems. Thus, this work also contributes towards the design and implementation of more resilient and economic power grids.…”

The electric power system is one of the cornerstones of modern society. One of its most serious malfunctions is the blackout, a catastrophic event that may disrupt a substantial portion of the system, playing havoc to human life and causing great economic losses. Thus, understanding the mechanisms leading to blackouts and creating a reliable and resilient power grid has been a major issue, attracting the attention of scientists, engineers, and stakeholders. In this paper, we study the blackout problem in power grids by considering a practical phase-oscillator model. This model allows one to simultaneously consider different types of power sources (e.g., traditional AC power plants and renewable power sources connected by DC/AC inverters) and different types of loads (e.g., consumers connected to distribution networks and consumers directly connected to power plants). We propose two new control strategies based on our model, one for traditional power grids and another one for smart grids. The control strategies show the efficient function of the fast-response energy storage systems in preventing and predicting blackouts in smart grids. This work provides innovative ideas which help us to build up a robuster and more economic smart power system.

Nowadays most distributed generators are not designed to operate under islanded conditions. The ancillary service of islanded operation capability is proposed as a technical support service with the ability to increase the reliability, security and flexibility of an electrical distribution system. Nevertheless, island operation entails technical, economic and social issues that must be discussed and analyzed during the planning stage.This article compares an intentional island project to a preplanned island and describes the main issues and benefits of islanded operation. Additionally, the reliability of the service to implement the islanded operation capability as an ancillary service is economically assessed, which shows that island-based operation has the potential to minimize nonsupplied energy up to 50%. Also, a technical analysis of implementing island operation capability ancillary service is presented. Subsequently, an existing electrical distribution system with small hydropower plants is considered as a study case in order to identify the technical requirements set out for both, the distribution system and the generation source. Finally, taking into account the current Law and regulations, a proposal is outlined for the implementation of the island operation capability ancillary service in the Colombian electrical system.

ResumenHoy en día, la mayoría de los generadores distribuidos no están diseñados para operar bajo condiciones de isla. El servicio complementario de capacidad de operación por islas se presenta como un servicio de soporte técnico con la capacidad de aumentar la resiliencia, confiabilidad, seguridad y flexibilidad de un sistema eléctrico de distribución. Sin embargo, la operación por islas presenta unos desafíos técnicos, económicos y sociales que deben discutirse y analizarse durante la etapa de planificación.En este artículo, se presenta una comparación entre una operación intencional por islas y una isla planificada previamente, así como una descripción de los principales desafíos y beneficios de la operación por islas. Además, se realiza una evaluación económica de la confiabilidad del servicio de energía eléctrica al implementar la capacidad de operación por islas como un servicio complementario. Dicha evaluación muestra que la operación por islas tiene el potencial de minimizar la energía no suministrada hasta en un 50%. Además, se muestra un análisis técnico para la implementación del servicio complementario de capacidad de operación por islas. Luego, se estudia un sistema eléctrico de distribución existente con pequeñas centrales hidroeléctricas como un estudio de caso, con el fin de identificar los requisitos técnicos establecidos tanto para el sistema de distribución como para la fuente de generación. Finalmente, y teniendo en cuenta las normativas y regulaciones vigentes, se esboza una propuesta para la implementación del servicio complementario de capacidad de op...
