Selected Problems of Modelling Energy Storage and Renewable Sources for Long-Term Analyses

The development of power system models for long-term analyses require taking into account tool requirements, limitations of calculations and, at the same time, obtaining the best possible representations of parameters. This often requires appropriate preparations, including time-consuming adjustments on the part of researchers. The article presents the results related to the selection of the time series mapping method for modelling system development plans, in particular the assessment of the balance of renewable energy generation and energy storage.
