Hasta el momento esta transformaci\u00f3n se ha dado manteniendo los par\u00e1metros tradicionales en cuanto a tama\u00f1o y ubicaci\u00f3n de las centrales de generaci\u00f3n. Se construyen centrales de varias decenas o centenas de MW, tanto solares como e\u00f3licos, ubicados en los sitios de mejor recurso y luego se deben construir l\u00edneas de transmisi\u00f3n para llevar su producci\u00f3n a los centros de consumo<\/p>\n<p>Actualmente se est\u00e1 reglamentando una ley sobre Generaci\u00f3n Distribuida que apunta b\u00e1sicamente a la microgeneraci\u00f3n (generadores del orden de algunos kW), entendi\u00e9ndose en este caso como \u201cdistribuida\u201d porque la energ\u00eda se genera en el propio consumidor, o una zona aleda\u00f1a al mismo.<\/p>\n<p>Sin embargo, puede existir \u201cOtra Generaci\u00f3n Distribuida\u201d, una soluci\u00f3n intermedia que consiste en centrales de generaci\u00f3n de algunos MW ubicadas en las cercan\u00edas de los Centros de Consumo, como\u00a0 son las poblaciones del interior del pa\u00eds.<\/p>\n<p>Se puede sacar provecho de que los parques e\u00f3licos o solares en forma independiente, m\u00e1s all\u00e1 de su tama\u00f1o, se componen siempre por unidades de relativamente poca potencia (algunos MW), ya que los aerogeneradores tienden a oscilar entre 2 \u00f3 4 MW de potencia.<\/p>\n<p>Esta caracter\u00edstica hace que los beneficios de construir parques de gran escala no sean tan importantes. Debido a esto es posible que el costo por MW instalado de un parque de 10 MW o menos, no var\u00ede demasiado al de un parque de 100 MW o m\u00e1s.<\/p>\n<p>La Conexi\u00f3n a un sistema de trasmisi\u00f3n de un parque de 15 MW \u00a0o menos se puede \u00a0hacer directamente en las redes de distribuci\u00f3n ya que \u00a0las unidades de generaci\u00f3n e\u00f3lica suelen generar a 30 kV o menos y los inversores de las plantas solares tambi\u00e9n.<\/p>\n<p>La energ\u00eda producida por parques e\u00f3licos o solares conectados en redes de distribuci\u00f3n, se consumir\u00e1 seguramente en centros de consumo tambi\u00e9n conectados a esa red de distribuci\u00f3n. Por lo que en este caso se est\u00e1 evitando que esa energ\u00eda tenga que transitar las redes de trasmisi\u00f3n. Adem\u00e1s, las l\u00edneas de distribuci\u00f3n alejadas de los centros de generaci\u00f3n suelen sufrir problemas de control de tensi\u00f3n, de estabilidad y de respaldo de potencia. Tal es el caso que, muchas veces, los sistemas deben recurrir a centrales de generaci\u00f3n t\u00e9rmica para resolver estos problemas. Los aerogeneradores modernos, al igual que las centrales de generaci\u00f3n fotovoltaica, tienen capacidad para resolver estos problemas de tensi\u00f3n y de estabilidad de las redes de distribuci\u00f3n. Por lo tanto, la instalaci\u00f3n de parques e\u00f3licos de peque\u00f1o porte o plantas solares cercanos a los centros de consumo es una soluci\u00f3n que tiende a resolver los problemas de la distribuci\u00f3n, y a su vez evita los problemas de saturaci\u00f3n de l\u00edneas de trasmisi\u00f3n.<\/p>\n<p>Una poblaci\u00f3n de 10.000 habitantes consume anualmente la misma energ\u00eda que produce un parque e\u00f3lico de 8 MW. Habr\u00e1 momentos en que el parque producir\u00e1 el doble que lo que consume esa ciudad, y momentos en que no se producir\u00e1 nada. Pero si consideramos que este est\u00e1 en la cercan\u00eda de una ciudad, habr\u00e1 momentos en que el parque alimentar\u00e1 a la ciudad, y otros en que estar\u00e1 inyectando energ\u00eda al sistema de trasmisi\u00f3n. Debe tenerse en cuenta que las estaciones transformadoras entre los 33 kV de la distribuci\u00f3n y los 132 kV de la trasmisi\u00f3n son bidireccionales, por lo que cuando el parque est\u00e1 trabajando a plena potencia y la poblaci\u00f3n aleda\u00f1a no consuma, la estaci\u00f3n transformadora, estar\u00e1 elevando una potencia similar a la que baja cuando el parque no trabaja y la poblaci\u00f3n consume al m\u00e1ximo.<\/p>\n<p>Aunque estos parques cercanos a poblaciones que constituyen \u201cLa Otra Generaci\u00f3n Distribuida\u201dno posean el mejor recurso, igualmente pueden generar a precios muy competitivos con la generaci\u00f3n tradicional.<\/p>\n<p>Ventus tiene experiencia comprobada en la construcci\u00f3n, y operaci\u00f3n &amp; mantenimiento de m\u00e1s de 20 centrales de generaci\u00f3n e\u00f3licas y solares de menos de 10 MW, que fueron construidas a costos de inversi\u00f3n por kW instalado menores que plantas de 50 \u00f3 70 MW.<\/p>\n<p>[\/tp]<\/p>\n<p>[tp lang=\u00bben\u00bb not_in=\u00bbes\u00bb]<\/p>\n<p><em>Opinion Column Oscar Ferre\u00f1o\u00a0<\/em><br \/>\n<em>Source: Energ\u00eda Estrat\u00e9gica<\/em><\/p>\n<p><img loading=\"lazy\" decoding=\"async\" class=\"aligncenter size-large wp-image-373\" src=\"https:\/\/ventusenergia.com\/blog\/wp-content\/uploads\/2016\/10\/VENTUS_Rosario_0192-1024x767.jpg\" alt=\"\" width=\"860\" height=\"644\" srcset=\"https:\/\/ventus.global\/blog\/wp-content\/uploads\/2016\/10\/VENTUS_Rosario_0192-1024x767.jpg 1024w, https:\/\/ventus.global\/blog\/wp-content\/uploads\/2016\/10\/VENTUS_Rosario_0192-300x225.jpg 300w, https:\/\/ventus.global\/blog\/wp-content\/uploads\/2016\/10\/VENTUS_Rosario_0192-400x300.jpg 400w\" sizes=\"auto, (max-width: 860px) 100vw, 860px\" \/><\/p>\n<p>Argentina is undergoing a deep energy transformation with the incorporation of Non-Conventional Renewable Energies, mainly wind and solar energy. So far this transformation has been taking place maintaining the traditional parameters in terms of size and location of the generation plants. Power plants of several tens or hundreds of MW are built, both solar and wind, located in the best resource sites and then transmission lines must be built to take their production to the consumption centers<\/p>\n<p>Currently, a Distributed Generation law is being regulated, which basically aims at microgeneration, understood in this case as \u00abdistributed\u00bb because the energy is generated by the consumer, or a nearby location.<\/p>\n<p>However, there may be \u00abAnother Distributed Generation\u00bb, an intermediate solution that consists of the construction of generation plants of some MW located \u00a0near Consumption Centers, such as the populations located in \u00a0the countryside.<\/p>\n<p>One advantage of this is the fact that wind or solar farms, beyond their size, are always composed of relatively low power units (some MW), since wind turbines tend to variate between 2 or 4 MW of power.<\/p>\n<p>This makes the benefits of building large-scale wind farm less important. Due to this, it is possible that the cost per installed MW or a farm of 10 MW or less does not vary too much from that of a park of 100 MW or more.<\/p>\n<p>The connection to a transmission system of a wind farm of 15 MW or less can be made directly in the distribution networks since the wind generation units usually generate at 30 kV or less as the inverters of the solar farms.<\/p>\n<p>The energy produced by wind or solar farms connected in distribution networks will surely be consumed in consumption centers also connected to that distribution network. The distribution lines away from the generation centers tend to suffer problems of voltage control, stability and power backup. Such is the case that, often, the systems must resort to thermal generation plants to solve these problems. Modern wind turbines, like the photovoltaic generation plants, have the capacity to solve these problems of tension and stability of the distribution networks. Therefore, the installation of small wind or solar farms close to the consumption centers is a solution that tends to solve the problems of distribution, and avoids the problems of saturation of transmission lines.<\/p>\n<p>A population of 10,000 inhabitants annually consumes the same energy produced by an 8 MW wind farm. There will be times when the farm will produce twice as much what city consumes, and times when nothing will happen. But if we consider that this is in the vicinity of a city, there will be times when the park will feed the city, and others in which it will be injecting energy into the transmission system. It should be taken into account that the transformer stations between the 33 kV of the distribution and the 132 kV of the transmission are bidirectional, so when the farm is working at full power and the surrounding population does not consume, the transformer station will be raising a power similar to the one that goes down when the park does not work and the population consumes to the maximum.<\/p>\n<p>Although these farms near populations that constitute \u00abThe Other Distributed Generation\u00bb do not have the best resource, they can also generate very competitive prices with traditional generation.<\/p>\n<p>Ventus has proven experience in the construction, operation and maintenance of more than 20 wind and solar power plants of less than 10 MW, which were built at investment costs per kW installed lower than 50 or 70 MW plants.<\/p>\n<p>[\/tp]<\/p>\n","protected":false},"excerpt":{"rendered":"<p>[tp lang=\u00bbes\u00bb not_in=\u00bben\u00bb] Columna de Opini\u00f3n Oscar Ferre\u00f1o Fuente: Energ\u00eda Estrat\u00e9gica La Argentina est\u00e1 viviendo una profunda transformaci\u00f3n energ\u00e9tica con la incorporaci\u00f3n de Energ\u00edas Renovables No Convencionales, fundamentalmente e\u00f3lica y solar.
