Tiivistelmä
Nowadays there are different ways of controlling a group of reactive power compensators at substation but most of them tend to be deterministic and rigid. In other words, they do not take into account the possibility of a change in the number of compensators operating at a given moment due to maintenance or switching of circuit breakers which alters configuration of the substation thus affecting the number of compensators electrically connected to the busbar. Also, the current control systems of the group of compensators do not take into account the current state of each individual device with regards to the circuit breaker’s on-off cycles which may lead to more frequent maintenance services. Furthermore, a decrease in the power losses in the compensators and minimization of harmonic input into the system from compensators such as variable shunt reactors are desirable as well.
These flaws of the regular control systems can be eliminated by using a multi-agent system technology. Therefore, in this thesis there will be developed a control system of a group of compensators using a multi-agent system that is adaptive to any changes in the substation and also deployment of which leads to an increase in the lifetime of the circuit breakers, and decrease in the power losses in the compensators, and minimization of harmonic input into the system by the compensators.
