Improving Renewable Generation Exploitation by Renewable Energy Communities Flexibility Services

The increasing penetration of Renewable Energy Sources (RESs) requires the development of novel services to strengthen the flexibility and resilience of power systems. In this paper, a linear and scalable model is proposed to determine renewable generation curtailment in radial distribution networks when flexibility services are offered by Renewable Energy Communities (RECs). The methodology is applied considering Virtual Islanding (VI), a coordinated operating service that allows RECs to remain connected to the grid while ensuring a zero net active power exchange with the distribution network. he proposed linear optimization approach quantifies the effect of VI in reducing renewable curtailment and enhancing RES utilization in a radial test network, improving the technical performance and sustainability of the distribution system.
