Clean energy

The penetration of renewable energy sources, particularly wind energy, into power systems has been rapidly increasing in recent years. This type of energy sources is relatively variable and unpredictable. Wind could, for example, be available at low-load periods and it may not be committed to supply power at peak-load hours, which results in a mismatch between generation and load. One of the actions that can be taken to support wind integration is the use of Energy Storage Systems (ESSs). In this paper, we formulate an AC Optimal Power Flow (OPF) problem with Battery Energy Storages (BESs) and then perform tests on IEEE 14-bus case study with different locations and numbers of BESs to discuss impacts of BES location on system operation.
