Description
Summary:Nowadays, in addition to a tendency to the use of renewable energy sources, there is also the tendency to operate these units in a decentralized manner so that they are able, if necessary, to work independently or in isolation from the rest of the power system. These systems are called microgrids (MGs). When using renewable energy sources, mainly based on solar radiation or wind, the problem is mainly the fluctuating and intermittent nature of these resources. In the case of MGs, this problem is particularly critical given the need of the ability to work in isolation. To operate MGs safely, a combination of several types of generators and also energy storage should be used to maintain the balance of active power. Among the new storage systems, sodium sulphur batteries (NAS) are considered suitable to perform various security tasks in MG.
