Battery storage systems can be utilized as flexible resources in the power system. Although many such systems are presently considered to be too expensive solutions in many cases, the prices are expected to drop.

Thus, battery storage systems have been considered for many case studies in CINELDI [1]–[9]: optimization of battery system operation, as an alternative to grid reinforcement, for enhancing security of supply, cost-optimal operation in prosumer villas, considering battery degradation and optimal operation of such systems in large buildings, such as a football stadium, for example.

EV batteries can be used both as a flexible resource [10], [11], either for voltage support, demand shifting or as a power plant through Vehicle2Grid.

The BATTPOWER toolbox was also developed in collaboration with CINELDI [12]. It is a multi-period AC optimal power flow (OPF) solver which takes various flexible resources such as stationary energy storage systems and EV charging into account and aims to be highly computationally efficient compared with traditional OPF solvers [13].
