[ES] La restructuración que han sufrido los sectores eléctricos a nivel mundial y las políticas energéticas que se plantean en el futuro en Europa, tienen como objetivo aumentar la competitividad de los consumidores mediante, entre otras acciones, conseguir precios de la electricidad más competitivos. Esta situación resulta especialmente delicada en España donde las carencias del sector eléctrico no han sido paliadas por la ley 54/1997 que modificaba la estructura del sector ni por las sucesivas modificaciones que se han planteado con posterioridad. La falta de transparencia en muchos procesos y la carencia de mecanismos de compra y venta de electricidad han sido dos factores clave de este fracaso. Además, una de las principales razones para este desajuste es precisamente la irrupción de un alto porcentaje de energías renovables en la generación y su deficiente tratamiento regulatorio. Como resultado de esto último surge una gran incertidumbre en los propietarios de los parques de generación renovable, en cuanto a su remuneración y condiciones de actividad. El objetivo principal que busca esta tesis es desarrollar una metodología que permita a los consumidores del sector industrial con unas determinadas características de elevado consumo energético y posibilidad de instalar generación renovable adicional, de planificar y gestionar de manera óptima y dinámica sus recursos y consumos energéticos en aras de un beneficio económico, social y ambiental. Esto implica, fundamentalmente, conocer su forma de consumir energía, flexibilidad en este consumo, así como los factores externos que pueden variarlo. Así mismo, tiene que tener información de los costes de operación del sistema de suministro de energía eléctrica en los que puede influir y de esta forma afrontar su principal reto que es tomar de forma anticipada las decisiones que le permitirá la optimización de su gasto energético participando a la vez en la mejora de los beneficios sociales y ambientales. / [CAT] Worldwide restructuring suffered by electrical sectors together with energy policies that are proposed for the future in Europe aim to an increase of the consumers competitiveness throughout, among other actions, achieving more competitive electricity prices. This is a critical situation in Spain where the shortcomings of the electricity sector have neither been alleviated under Law 54/1997, which modified the structure of the sector, nor with the successive modifications that have been raised subsequently. The lack of transparency in many processes and the lack of mechanisms for buying and selling electricity have been two key factors in this failure. Furthermore, one of the main reasons for this mismatch is precisely the emergence of a high percentage of renewable energy in the generation and its poor regulatory treatment. As a result, a great uncertainty arises in the owners of renewable generation parks, as far as their remuneration and activity conditions are concerned. The main objective of this PhD thesis is to develop a methodology that allows industrial consumers for certain characteristics of high energy consumption and the possibility of installing additional renewable generation, to plan and manage in an optimal and dynamic way their resources and energy consumption for the sake of an economic, social and environmental benefit. That implies, basically, knowing the way of consuming energy, the flexibility in the consumption, as well as the external factors that may vary it. Likewise, they need information on the operating costs of the electric power supply system on which they can have influence, and thus face the main challenge, which is to make in advance the decisions that will allow them to optimize energy expenditure by participating, at the same time, in the improvement of social and environmental benefits. / [EN] La reestructuració dels sectors elèctrics a nivell mundial i les polítiques energètiques que es plantegen en el futur a Europa, tenen com a objectiu augmentar la competitivitat dels consumidors mitjançant, entre altres accions, aconseguir preus de l'electricitat més competitius. Aquesta situació resulta especialment delicada a Espanya, on les carències del sector elèctric no han sigut pal·liades per la llei 54/1997 que modificava l'estructura del sector ni per les successives modificacions que s'han plantejat posteriorment. La falta de transparència en molts processos i la carència de mecanismes de compra i venda d'electricitat, han sigut dos factors clau d'aquest fracàs. A més, una de les principals raons per a aquest desajust és precisament la irrupció d'un alt percentatge d'energies renovables en la generació i el seu deficient tractament regulador. Com a resultat d'aquest últim fet, sorgeix una gran incertesa en els propietaris dels parcs de generació renovable, pel que fa a la seua remuneració i les seues condicions d'activitat. L'objectiu principal que busca aquesta tesi és desenvolupar una metodologia que permeta els consumidors del sector industrial amb unes determinades característiques d'elevat consum energètic i possibilitat d'instal·lar generació renovable addicional, planificar i gestionar d'una manera òptima i dinàmica els seus recursos i consums fonamentalment, conèixer la seua forma de consumir energia, flexibilitat en aquest consum, així com els factors externs que poden variar-lo.
