DESCRIPTION
 
In recent years, the different facilities that the  Energy Technological Institute (ITE) has in Paterna (Valencia) have evolved progressively adopting a micro-network structure, equipped with different systems of generation, storage and consumption.
 
The Renewable Energy Pilot Plant constitutes a point of distributed generation (DER), allowing the realization of tests and validation of equipment, systems and management strategies, among them the dispatch of distributed generation.
 
It includes a photovoltaic plant (7.5 kW), mini-wind turbines with horizontal axis (6 kW), and vertical (1 kW), and two PEM hydrogen batteries (1.2 kW and 4.5 kW). All this is combined with an energy storage system with batteries of different technologies, supercapacitors and hydrogen vector (under pressure and in metal hydrides).
 
There is also an industrial frequency network simulator and another DC network simulator.
 
In terms of power consumption elements, it has a dedicated line for simulating domestic consumption, equipped with manageable appliances, smart plugs and consumption monitoring equipment. The main objective is the application and validation of techniques and algorithms for active management of the demand in the home, by sending signals of limitation or power switch off to the different appliances, although it is also prepared for other studies. as the electrical characterization of domestic equipment.
 
On the other hand, the ITE building itself is seen as an Active Self-Managed Node with the capacity to monitor and manage its consumption and generation at the local level, with the following objectives:
 
- Improvement of energy efficiency and consumption reduction.
- Promotion of the use and viable integration of renewable energies and storage systems.
- Automated management of resources and functionalities through the design of local control systems directed by a single intelligent centralized artificial manager to balance the energy in buildings.
 
The Interoperability Laboratory has a set of passive, resistive and inductive loads. Two unique installations allow obtaining load situations close to reality, as the BT network can be configured in different topologies and line lengths, allowing to analyze the behavior in the management of loads and communications over the network, especially for Smart-metering. This laboratory provides a platform to verify the correct functionality of a Smart Grid through its various applications:
 
- PLC-based interoperability (PRIME, DLMS / COSEM).
- Supervision and maintenance for Smart Secondary Substations.
- Certification of energy meters
- Monitoring of microgrids.
 
The implemented communications network has an architecture parallel to the PRIME communication with monitoring and recording of individualized energy consumption, actuation devices and line switches, visualization and remote control of signals of the air conditioning equipment, and additional sensorization for detection of people through photocells, water consumption, and a webcam with IP communication.
 
SERVICES OFFERED
 
The entire system is an instrumented environment for the realization of research and development projects, both own and of other companies, allowing the development and validation of products, systems and algorithms that configure smartgrids in areas such as:
 
- Management and characterization (electric signature) of domestic loads
- Communications between distribution meter and operator based on PRIME standard on PLC
- Integration of devices in microgrids
- Grid Integration of renewable energies
- Energy storage systems (batteries, hydrogen vector, ...)
- Integration of electric vehicle
- Algorithms for demand side management
