Abstract
A large quantity of variable renewable energy sources (RESs), most notably wind and solar, is now connected to the Portuguese network system, which makes it somehow unique. Yet, in the coming years, the network is expected to accommodate more of these and other technologies of “clean” power productions. The deployment and efficient utilization of various flexibility options are certainly required in a system experiencing such levels of dynamic changes so as to ensure a standard level of service provision in terms of security, stability and reliability. Among these is a battery energy storage system (BESS), which is emerging as one of the most viable and effective options of increasing the much-needed flexibility in power systems. This work aims to assess the impact of deploying BESSs on the operational performance of the Portuguese transmission grid, mainly in terms operational flexibility and variable RES power support. In particular, the potential benefits of strategically placed BESSs are investigated using a stochastic optimization framework. Numerical results show that integrating BESSs leads to a more efficient use of renewable power by considerably minimizing curtailments, and a 10% reduction in system-wide cost. Energy losses are moderately increased as a result of the BESS deployment. But this is offset by the savings in operation and emission costs.
