Development and Utilization of a Quasi-dynamic Model for Power System Analysis

Nowadays the Quasi-Dynamic Simulation is widely used in international practice to analyze the impact of intermittent generation on the grid. The application of quasi-dynamic simulation allows considering the system load curve, generation profile, storage systems, and operation of renewables in the area as well. These results are a more realistic estimation of generation considering the period of interest (day, week, month, season, year, etc.). However, in comparison with the simple dataset for the traditional deterministic approach, quasi-Dynamic Simulation requires much more data and a need to develop more complex models. Additionally, the application of the comprehensive model of the PV system allows considering time-series data of the real irradiation level measured for each hour of the year for the latitude and longitude of the PV plant location.
