Caracteriza a la presente invención el especial diseño, configuración, funcionalidad e interacción entre los diferentes elementos que forman parte de la invención. The present invention is characterized by the special design, configuration, functionality and interaction between the different elements that form part of the invention.
Por lo tanto, la presente invención se circunscribe dentro del ámbito de los sistemas de generación de energía eléctrica que integran vahas fuentes de suministro. Therefore, the present invention is circumscribed within the scope of electric power generation systems that integrate various supply sources.
ANTECEDENTES DE LA INVENCIÓN BACKGROUND OF THE INVENTION
En el estado de la técnica son de sobra conocidas las plantas de producción de energía solar fotovoltaica, que presenta una serie de ventajas en inconvenientes como los que a continuación exponemos. In the state of the art, photovoltaic solar energy production plants are well known, which have a series of advantages as well as drawbacks such as those that we present below.
Su principal ventaja frente a otros sistemas solares es que funcionan con la radiación lumínica, no necesitan la incidencia directa del rayo solar, por lo que, en días nublados, incluso lluviosos, reducen su productividad, pero no dejan de funcionar. Its main advantage over other solar systems is that they work with light radiation, they do not need the direct incidence of sunlight, so that, on cloudy days, even rainy, they reduce their productivity, but they do not stop working.
Los requisitos de mantenimiento son muy bajos y, en la mayoría de situaciones, no necesita personal muy especializado.
La limpieza de los paneles solares fotovoltaicos es simple, además existe la posibilidad de seguimiento con uno o dos ejes, eliminando el efecto de la incidencia del ángulo del sol, pudiéndose combinar con sistemas de almacenamiento eléctrico. Maintenance requirements are very low and, in most situations, you do not need highly specialized personnel. Cleaning photovoltaic solar panels is simple, and there is also the possibility of tracking with one or two axes, eliminating the effect of the incidence of the angle of the sun, and can be combined with electrical storage systems.
El único inconveniente que presentan es que precisan de grandes extensiones de terreno. The only drawback they present is that they require large extensions of land.
Por otro lado, también son conocidos los sistemas de generación de electricidad mediante el empleo de turbinas de hidrógeno y/o biogás. On the other hand, electricity generation systems using hydrogen and/or biogas turbines are also known.
Estos sistemas de generación de electricidad a partir de turbinas de hidrógeno y/o biogás presentan la situación de contar con un suministro asegurado, ya que, aunque el biogás se suministra conducido por tuberías por el proveedor, el hidrógeno se debe producir in situ o/y almacenarse en tanques para el caso de que la autoproducción no sea la suficiente para cubrir la demanda de las turbinas. These electricity generation systems from hydrogen and/or biogas turbines present the situation of having a guaranteed supply, since, although the biogas is supplied through pipelines by the supplier, the hydrogen must be produced on site or/ and stored in tanks in case self-production is not enough to cover the demand of the turbines.
Por otro lado, a nadie hasta el momento se le ha ocurrido la integración de ambas formas de generación de energía eléctrica de manera que asegure una producción y suministro regular y suficiente basado en energía solar fotovoltaica y turbinas de hidrógeno y/o biogás. On the other hand, to date no one has thought of integrating both forms of electricity generation in such a way as to ensure regular and sufficient production and supply based on photovoltaic solar energy and hydrogen and/or biogas turbines.
La integración de ambos medios de producción de energía eléctrica necesita de una gestión eficiente que anticipe de manera sencilla y eficaz el consumo para asegurar un suministro continuo y estable. Todo ello precisa de unos medios de toma de datos sobre patrones de consumo, picos de consumo, costumbres de los usuarios, etc que con el software adecuado, se conviertan en la información necesaria para ser utilizada en la gestión eficiente de la planta. The integration of both means of electricity production requires efficient management that anticipates consumption in a simple and effective way to ensure a continuous and stable supply. All of this requires means of collecting data on consumption patterns, consumption peaks, user habits, etc., which, with the appropriate software, become the necessary information to be used in the efficient management of the plant.
Por lo tanto, es objeto de la presente invención desarrollar una planta de generación de energía eléctrica que integre unos medios de producción de energía fotovoltaica por un lado y unos medios de producción de energía eléctrica a partir de turbinas de hidrógeno y/o biogás que permitan solucionar los problemas planteados y logre una optimización de producción y costes basados en consumos reales centralizados, desarrollando una planta de generación híbrida e inteligente como la que a
continuación se describe y queda recogida en su esencialidad en la reivindicación primera.

These means of data collection They consist of a series of sensors that transmit information in real time, which are analyzed by specific software and used by the production management system (VIRTUAL POWER PLANT) to optimize the means of production.
El empleo de energía solar fotovoltaica presenta varias ventajas, por un lado, el hecho de que funciona con luz, no necesita la incidencia directa de la radiación solar, por otro lado, requiere un mantenimiento muy bajo y sin personal especializado en la mayoría de los casos, además permite la instalación con seguimiento a uno o dos ejes y permite la combinación con sistemas de almacenamiento eléctrico, tales como baterías. The use of photovoltaic solar energy has several advantages, on the one hand, the fact that it works with light, it does not need the direct incidence of solar radiation, on the other hand, it requires very low maintenance and without specialized personnel in most of the cases, it also allows installation with one or two axis tracking and allows combination with electrical storage systems, such as batteries.
El empleo de baterías como medio de almacenamiento eléctrico da una gran versatilidad a los sistemas de generación eléctrica de forma directa, tales como los sistemas de generación fotovoltaicos. Las baterías permiten almacenar energía en las horas de bajo consumo y poder cederla en horas punta, además permite atender suministros en situaciones de alto consumo y poca duración, permite nivelar posibles picos y garantizar, junto con el regulador, la estabilidad de funcionamiento del conjunto de la planta. The use of batteries as a means of electrical storage gives great versatility to direct electrical generation systems, such as photovoltaic generation systems. Batteries allow energy to be stored during hours of low consumption and to be able to transfer it at peak hours, it also allows supplies to be met in situations of high consumption and short duration, allows to level out possible peaks and guarantee, together with the regulator, the operating stability of the set of plant.
Las baterías tienen como inconveniente que pueden llegar a ser el elemento más caro de una instalación y su vida útil depende de los ciclos de carga. Batteries have the drawback that they can become the most expensive element in an installation and their useful life depends on the charging cycles.
Las turbinas de gas, preferentemente serán turbinas mixtas de hidrógeno y biogás o hidrógeno sólo, ofrecen una gran fiabilidad, son modulables y se instalan en serie hasta alcanzar la potencia deseada, se instalan fácilmente, sólo necesitan una conexión de hidrógeno / biogás y otra de agua para recuperar el calor de “exhaustación” en caso que se quiera utilizar. The gas turbines, preferably mixed hydrogen and biogas turbines or hydrogen alone, offer great reliability, are modular and can be installed in series until the desired power is reached, they are easy to install, they only need a hydrogen/biogas connection and another water to recover the heat of "exhaustion" in case you want to use it.
El sistema de gestión de la producción de la planta en combinación con los medios de toma de datos relativos a consumos, picos y costumbres de consumo y con la estación meteorológica, producen un efecto sinérgico sobre la planta híbrida, ya que permite “ param etrizar”, programar y controlar con antelación la producción de energía en
función de los datos obtenidos, de manera que se consigue una gestión eficiente, que anticipa de manera sencilla y eficaz el consumo para asegurar un suministro continuo y una rápida capacidad de respuesta en caso de desviaciones con las previsiones. The production management system of the plant in combination with the means of data collection related to consumption, peaks and consumption habits and with the weather station, produce a synergistic effect on the hybrid plant, since it allows "parameterization" , program and control in advance the production of energy in based on the data obtained, so that efficient management is achieved, which anticipates consumption in a simple and effective way to ensure continuous supply and a rapid response capacity in the event of deviations from forecasts.
Este sistema de planta híbrida e inteligente se basa en combinar diferentes fuentes de energía en un flujo de demanda de electricidad que se gestiona con la ayuda de la tecnología adecuada. This hybrid and intelligent plant system is based on combining different energy sources in a flow of electricity demand that is managed with the help of the appropriate technology.
Permite gestionar la demanda de energía de los usuarios a los que se suministra y paliar las posibles interrupciones de la red. It allows managing the energy demand of the users to whom it is supplied and mitigating possible interruptions in the network.
Esta planta permite, además, reducir los costes de producción, una mayor flexibilidad en la generación total y una minimización de las pérdidas en el transporte al estar situada próxima a los puntos de consumo. This plant also allows for reduced production costs, greater flexibility in total generation and minimization of transport losses as it is located close to the points of consumption.
Otra de las ventajas y novedades de este diseño de planta, es el aprovechamiento total de la capacidad productiva de la planta fotovoltaica y la no dependencia de la evacuación y venta de los excedentes de producción eliminando el efecto “dumping”, a través de la conversión de la energía sobrante, en la producción de hidrógeno por electrólisis, convirtiendo a este en un vector que le da la continuidad de producción a la planta en horas de no radiación lumínica. Another of the advantages and novelties of this plant design is the full use of the productive capacity of the photovoltaic plant and the non-dependence on the evacuation and sale of surplus production, eliminating the "dumping" effect, through the conversion of the surplus energy, in the production of hydrogen by electrolysis, turning this into a vector that gives the plant continuity of production in hours of no light radiation.
Como es sabido, la capacidad productiva de la tecnología fotovoltaica se reduce a las horas de luz, la única solución aplicada en plantas similares es el almacenamiento en baterías, con las consiguientes limitaciones técnicas y económicas que presentan las opciones existentes en el mercado hoy día. As is known, the productive capacity of photovoltaic technology is reduced to hours of light, the only solution applied in similar plants is battery storage, with the consequent technical and economic limitations presented by the options on the market today.
El alto coste actual de las baterías limita totalmente la capacidad de almacenamiento de una instalación ya que, junto a su, relativamente, corto ciclo de vida y la reducción de rendimiento (capacidad de almacenaje) hacen muy difícil un dimensionamiento realmente aprovechable y útil para evacuación y vertido a la red de la energía almacenada.
Este diseño nos permite utilizar los excedentes de producción, es decir la energía que produce la planta fotovoltaica y que no es consumida al momento, no sólo para la carga de las baterías en el momento óptimo, sino que, además, alimenta a la planta de electrólisis para la producción del hidrógeno que consumirán las turbinas cuando sean requeridas. The current high cost of batteries totally limits the storage capacity of an installation since, together with their relatively short life cycle and reduced performance (storage capacity), they make it very difficult to dimension them in a way that is really usable and useful for evacuation. and discharge to the network of the stored energy. This design allows us to use production surpluses, that is, the energy produced by the photovoltaic plant and not consumed at the moment, not only to charge the batteries at the optimum moment, but also to feed the power plant. electrolysis for the production of hydrogen that will be consumed by the turbines when required.
Por todo esto y por la minimización de las pérdidas en transporte debido a la proximidad de los puntos de consumo, este diseño de planta aprovecha su capacidad productiva al máximo posible con las tecnologías aplicadas convirtiéndola en una UNIDAD ESTRATÉGICA EN LA PRODUCCIÓN ENERGÉTICA. For all this and for the minimization of transport losses due to the proximity of consumption points, this plant design takes advantage of its productive capacity to the maximum possible with the applied technologies, turning it into a STRATEGIC UNIT IN ENERGY PRODUCTION.
Los medios de toma de datos relativos a los consumos, picos de demanda y costumbres de consumo de la comunidad o instalación que se busca alimentar, también conocidos como “SMART GRID” permiten: The means of collecting data related to consumption, demand peaks and consumption habits of the community or facility to be fed, also known as "SMART GRID" allow:
