Unit Commitment and economic dispatch in micro grids
As a result of the differences between classical large power grids and micro grids a new approach of the Unit Commitment (UC) and Economic Dispatch (ED) problem must be proposed. The high penetrations of renewable sources and distributed energy storage systems, as well as the possibil...

| description | As a result of the differences between classical large power grids and micro grids a new approach of the Unit Commitment (UC) and Economic Dispatch (ED) problem must be proposed. The high penetrations of renewable sources and distributed energy storage systems, as well as the possibility of working in a grid-connected or island mode are some of the main issues to cope with. Firstly the advantages and drawbacks of the use of the Lambda Iteration Algorithm (LIA) for solving de ED problem in a micro grid are discussed. In order to adapt the LIA to this context some modifications have been carried out. With regard to the Unit Commitment problem, a genetic algorithm with some novel specific operators has been designed. This algorithm is suitable to deal with different constraints and scenarios arising in a micro grid environment. In addition, a comparison between the different characteristics of the designed UC algorithm and the traditional Priority List (PL) method has been performed. |

La fuerte presencia de energías renovables, la incorporación de sistemas de almacenamiento distribuidos y la posibilidad de que la micro red trabaje en isla o interconectada a la red principal son algunos de los aspectos a tener en cuenta a la hora de resolver dichos problemas. Primeramente se analizan las ventajas y desventajas del empleo del Algoritmo de Iteración Lambda (AIL) en la resolución de Despacho Económico, proponiéndose además modificaciones para adaptar el mismo al contexto de las micro redes. En lo que respecta a la resolución del despacho de unidades el artículo propone un algoritmo genético el cual emplea ciertos operadores que facilitan el tratamiento de las restricciones que surgen en este nuevo contexto. Finalmente se lleva a cabo una comparación entre el método de Lista de Prioridades (LP) y el algoritmo genético desarrollado.
