This paper deals with the well-based mathematical formulation of active and reactive load sharing of the synchronised generators of a ship’s electric energy system. Thus, both the first- and second-stage regulation during load sharing is presented via mathematical equations. The novelty introduced in the paper is, on the one hand, that the hybrid parallel operation of shaft and conventional generators is covered, while on the other hand, that the analysis results in solving the combined reactive and real load sharing within the generator rated capacity. Furthermore, the dynamic behaviour of the machines and their controllers during the load sharing problem is also discussed with the aid of simulations in the MATLAB/Simulink environment. The entire analysis, which it is hoped can also be used for educational purposes, is enriched by figurative results obtained from an actual ship case study, in which this work assisted in resolving a series of load sharing problems
