Estimation of small scale HPP affect on distribution network reliability under market conditions

Mathematical model of small scale HPP was developed for simulation of HPP electricity production in market conditions. Paper also presents approach for evaluation of power supply reservation possibility in distribution network using small scale HPP that operates in liberalized market conditions. Proposed approach allows evaluate theoretical possibility of HPP to improve reliability of power supply of distribution network in case of HV substation outage. Calculations for example with real HPP and distribution network were performed using proposed approach. Results of calculations showed that amount of possible reserved energy using small scale HPP is strongly dependant on type of generator installed at HPP and usage of smart grid technologies in distribution network.
