“…El establecimiento de procedimientos que hagan posible la participación activa de la demanda por parte de los consumidores hace que no solo sean informados de los precios para que puedan reaccionar ante los mismos, sino que además contribuyan activamente a la formación de estos, además de poder proporcionar servicios al conjunto del sistema eléctrico con valor de mercado, como la interrupción en situaciones de emergencia, o para resolver congestiones, proveer reservas de operación y participar en la gestión de desvíos o de la compensación de energía reactiva (Pérez, y otros, 2007;Carmeli, Marco, Catellif, Marchegiani, & Rosati, 2012).…”

. (2014). Aplicación de los sistemas fotovoltaicos conectados a la red: estado del arte. Revista Tecnura, Edición especial, 157-172. ResumenEn este trabajo se describen todos los conceptos necesarios para lograr implementar un sistema fotovoltaico como alternativa para ser utilizado como generador distribuido. Para ello, se realiza un pequeño estado del arte en el cual se manejan conceptos básicos, desde el funcionamiento de una celda solar hasta conceptos de redes inteligentes aplicados en la gestión de la demanda. Asimismo, se abarca un repaso sobre los marcos regulatorios existentes en Colombia, donde se habla de generación distribuida debido a la falta del mismo. Es necesario comparar tales regulaciones con los diferentes marcos regulatorios existentes en otros países, como Alemania, España y EE.UU., para obtener un modelo de trabajo idóneo. Finalmente, se decide utilizar un generador fotovoltaico conectado a la red de baja tensión como alternativa en los sistemas de generación distribuida, ya que con estos se pueden realizar balances energéticos, esto en caso de que en el país en donde se emplee esta alternativa no se tenga establecido un marco regulatorio adecuado, de manera que el usuario no tenga problemas con las entidades regulatorias actuales. Palabras clave: balance energético, energías renovables, generación distribuida, gestión de la demanda, sistemas fotovoltaicos. AbstractThis paper outlines all necessary concepts to successfully implement a photovoltaic system as an alternative in a distributed generation scheme. For this purpose, it is made a short state of the art in which basic concepts are addressed, from a solar cell operation to smart grid concepts applied on demand management. Likewise, a review of the different regulatory frameworks in Colombia is entailed, especially those related to distributed generation, due to the lack of these ones. It is necessary to make a comparison with other regulations from other countries,

Solar power sharing between two PV systems in a solar pyramid micro-grid

The hybrid PV system (HyPV) is a solar PV system for self-consumption which operates at stand-alone PV mode or grid mode automatically and does not feed access PV power into grid. HyPV operates at PV mode when solar radiation or battery energy is high enough. It switches to grid mode when battery storage is low. There may be a PV generation loss if the system match between load and sizes of battery and PV modules is not proper. We proposed a networking technique, called "solar pyramid micro-grid", which connects neighbor HyPVs, and shares solar PV power each other. The binary connection of HyPVs is the simplest design to build a solar pyramid micro-grid. Solar PV power generation of HyPVs can be shared each other through a switching control. In the present study, the binary connection of two HyPV systems at A-level (called "Hynet-2A") was built and tested. The test results show that the sharing of access solar PV power each other can effectively increase the PV power generation of the whole micro-grid system. The longterm solar PV energy generation of Hynet-2A is close to that of grid-tied solar PV systems.

“…In the second approach, various strategies are proposed especially for local optimization, coordination of sources and control of the load [1] [7], [8], [9], [10]. The optimization by accepting a load shedding is also studied [11] as well as the availability on the market of equipment [8] In some cases a shedding not larger than 5% may impact strongly on the cost (Bilal and al. 2013).…”

This paper describes the control of the energy transfers in Systems of Multiple Sources of Energy (SMSE). The considered SMSE is a Linear Time Varying (LTV) system in view of the sources and load fluctuations. The proposed control scheme includes DC bus voltage and current regulations loops as well as the automatic adjustment of the power ratio associated with each source. DC bus voltage and current regulations loops are carried out by generalized adaptive PID controllers. The calculation of the power ratios is computed with a Model Predictive Controller (MPC) designed to optimize the system overall performance
