Hydroelectric Power Generation for Compensation Instability of Non-guaranteed Power Plants

This paper presented research small- and mini-hydroelectric power plants as an effective source of compensation for instability of non-guaranteed renewable energy sources (RES) power plants. HPPs play the main role for balancing the power system operation mode. To somehow compensate for the growth of RES generation in the power system, we can forced to start hydropower plants as a consumer in the pump mode. This paper investigated the trends of installed capacity hydroelectric power plants (HPPs) for World and for Ukraine. Also, it was considered the dynamics of change of the annual amount of hydroelectric power generation (HPG) on data International Renewable Energy Agency (IRENA) for World and for Ukraine. Is shown the classification of HPPs on value green tariff and installed capacity. Observed the distribution of the daily power generation during the 2019 year by typical mini-HPP. Compared the experimental and calculation value power generation by typical mini-HPP in 2019. Researched of influence the meteorological factors on power generation of mini-hydropower plants using Spearman's rank correlation. Proposed for HPG used cascade small- and mini HPPs.
