Steady-State Stability of Industrial Distributed Generation Sources in Terms of Optimization of Their Active and Reactive Power Loading

One of the main requirements for industrial sources of distributed generation in normal condition is their optimal operation. The optimization criteria are determined by the operating conditions of the plant including the availability of waste energy and natural sources of fuel. Another requirement for power sources is the preservation of a given stock of static stability for active power. In the implementation of optimization measures, constantly changing load on generators active and reactive power that entails a change in maximum electromagnetic power of the machine. This article describes the algorithm of limitations on the static stability of synchronous generators in determining the optimal active and reactive power of its own sources of distributed generation in the power supply system of the industrial enterprise of iron works. The stability analysis was carried out with the help of the original software by the example of an industrial power supply system of a complex configuration with its own power stations having primary engines of various kinds. Based on the results of the analysis of static stability of synchronous generators by the method of sequential weighting, it is concluded that optimal conditions are permissible under the condition of stable operation under different conditions of communication with the electric power system.
