The article contains an analysis of power generation by a photovoltaic system with peak 3 MWp and wind turbine 3.45 MW. acquired time series generated was analyzed using traditional modern analytical methods. these two Renewable Energy Sources characterized separately then their mix. In this article, the signature defined as in state space over period one month. extracted from results cluster analysis. experiment clustering carried out into 10 classes. K-Means algorithm used to determine clusters variant without prior labeling classes method learning participation teacher. way, trajectories process were determined 10-state space. Knowing which class each data record belongs to, frequencies staying determined. computational presented may have great practical application balancing grid powered energy produced renewable sources.

In the introduction to this article, a brief overview of generated energy and power produced by photovoltaic systems with peak 3 MWp different tilt orientation panels is given. The characteristics latest generating wind turbines capacity 3.45 MW are also presented. subsequent stages research, necessity balancing in networks powered mix renewable sources demonstrated. Then, calculation algorithm presented area system photovoltaic–wind feeding low-emission hydrogen production process. It analytically graphically demonstrated that process entire can be influenced structural changes installation panels. proven angle have significant impact on level and, thus, individual hourly intervals. Research has implementation planned design assembly allows for reduction size storage more than 2 MWh. authors apply actual measurement data from specific geographical context, i.e., Lublin region Poland. calculations use both traditional statistical methods probabilistic analysis. Balancing month considered intervals throughout day essence made authors.
