Use of all-mode modeling complex for power systems with distributed generation

Today, the number of distributed generation facilities in the world is growing mainly due to renewable energy sources. However, the integration of a large volume of distributed generation (on the basis of wind power plants) into the existing electric power systems of power grids is associated with a number of significant problems. A comprehensive study and absolute solution of these problems require to conduct a detailed simulation of real electric power systems, which is impossible with the use of existing means. Therefore, for this purpose, the article proposes to use an alternative solution - an All-Mode real time modeling complex of power systems (AMRTMC PS). The conducted experimental studies involved the comparison of the modeling results of a small test circuit of electric power systems obtained by means of the AMRTMC PS and a widely used digital software and hardware complex RTDS. The article partially presents the results of complex comparison when reproducing similar models of electric power systems in both complexes, which confirm the adequacy of the information about the processes in equipment and electric power systems in general obtained by means of the real-time all-mode modeling complex of electric power systems. It is proved that the further application of the real-time all-mode modeling complex of electric power systems as a tool for detailed and adequate modeling of real electric power systems with distributed generation will provide complete and reliable information about normal and abnormal quasi-steady-state and transient processes in electric power systems with distributed generation, which is necessary for reliable and effective solution of design problems, research and subsequent operation of electric power systems with distributed generation.
