Article Description

With the increasing participation of renewable energy sources in electricity production, the answer to the question of the required capacity of the operational reserve in electric power systems is becoming more complicated. The mere variability of operational energy in photovoltaic, wind, and small hydroelectric power plants makes the required operational reserve capacity variable. For this reason, the need for an operational reserve in electric power systems from the aspect of renewable energy sources and in relation to microgrids is best addressed through the tools of probability, i.e., statistics and estimation. The question of the operating reserve in the electric power system was investigated by Bayesian statistics, which links the simultaneous occurrence of a random variable (available capacity of renewable energy sources in microgrids) with a statistical variable (electrical load power in microgrids). The result of the proposed algorithm is the probability of the deficit or surplus of available energy in the form of active and reactive electric power in microgrids, and the consequence of this probability is the probability of the need and degree of engagement of the operating reserve using thermal and hydroelectric power stations.
