Abstract

Over the years, the distribution grid has changed considerably. Today, the great production of energy by Renewable Energy Sources that produce fluctuating power into the distribution grid requires a greater ability to manage the low voltage section of the grid, since energy producers and users are more and more connected to the low voltage grid. Today the role of the power grid customer, whether producer, user, or prosumer, is central in the sustainable and reliable management of a modern distribution grid. The HYPERRIDE project in the Italian pilot develops a hybrid Alternate Current(AC)/Direct Current (DC) distribution grid that matches the needs of AC and DC users/prosumers with the needs of Distribution System Operator (DSO) to limit congestions at the nodes of the grid and promote the local consumption of the energy self-produced. The achievement of this synergy is based on flexibility criteria provided by the grid customers. Flexibility in consumption and production by the customers increases the sustainability and resilience of the grid as a whole, with impact mainly on Low Voltage (LV) grid but with benefits also on Medium Voltage (MV) grid at an upper level of hierarchy in the power grid. The effect of local variations in the hybrid AC/DC grid will be related to the effects on the entire grid, including the MV section. The selection of DC/DC and AC/DC converters, hybrid grid architecture, protections, monitoring and control systems is based on reliability and multi-operability requirements of all the systems involved. The pilot performance evaluation will be related to the fixed objectives in order to detect the deviations from the expected results and if necessary implement corrective actions and different settings in the equipment operating thresholds. The modern conventional grid is by nature a dynamic and adaptive system, the hybrid grid is even more so. The adaptive behaviour of the AC/DC hybrid distribution grid is in compliance with the requirements of the existing real AC distribution grid to improve the reliability of the whole system and therefore supply better services to the grid customers. The pilot set-up and test specification sets the Use Cases requirements to achieve and evaluate the synergy between all systems involved in the project.The impact of the new DC grid will be also evaluated in the real distribution grid operation. The definition of the pilot setup and test specifications is the result of a close collaboration with Work Package (WP) 2 and the identification of three use cases to test the integration requirements and validate them in a real distribution grid where coexist electric vehicle charging systems, Photovoltaic (PV) power plants, storage systems, critical loads and a DC system control infrastructure dedicated to the pilot. In addition, all required additional equipment including sensors, AC controllers, Application Programming Interface (API) and other hardware modules implemented or existing in the pilot will be tested.
