Project: Control of Virtual synchronous photovoltaic power plants with energy storage
Challenge:
The development of practically synchronous photovoltaic power plants will allow solving the problems that will currently be generated by a high penetration of conventional photovoltaic power plants in the electricity network, mainly from the point of view of the stability of the network, through the provision of new functionalities and services. . This is a priority objective to achieve the goals set in H2020, especially those related to reaching 20% of the installed capacity from renewables, since photovoltaics is the technology with the most potential after wind .
Solution:
• Expand the synchronous controller at the plant level, allowing a photovoltaic plant to offer practically synchronous performance.
• Analyze and develop a distributed control system of the practically synchronous plant capable of managing all the processes of the energy conversion chain, taking into account the automatic operation of the plant, the interaction with the grid and even its relation to the energy markets.
• Expand the concept of transactional power and develop new optimization algorithms based on sharing, in a competitive way, all the functionalities between all the elements that make up the plant, thus enhancing the overall efficiency of the system.
• Analyze and build a secondary control layer of the plant that takes into account synchronous performance and distributes functions accordingly between the different units also following a competitive criterion.
• Analyze and design cluster-level control algorithms to optimally perform and share the control tasks associated with the secondary control response.
• Develop intelligent algorithms to process information collected from the power plant and use it to perform predictive operations and maintenance.
• Analyze the sizing criteria and control requirements associated with the integration and management of the energy storage system that should form part of the practically synchronous photovoltaic plant.
• Analyze the impact of practically synchronous photovoltaic power stations on the electricity grid, and compare it with the effect of conventional ones.
• Analyze the additional functionalities that this type of plant would provide, mainly those related to frequency control and auxiliary services.
