САЖЕТАК / ABSTRACT:
Improvement of exploitation of existing HPPs is important task. One of the most interesting aspects is improvement of overall efficiency of HPPs steady-state regimes. Achievement of higher efficiency results in reduction of water consumption. The saved and stored water allows for additional energy generation at the HPPs. The paper presents methodology for analysing optimal intra-station regimes of HPPs (a.k.a. optimal unit allocation/dispatching) availing with asymmetric energetic haracteristics of gen-units and waterways, i.e. the HPPs developed and commissioned in two stages, run-of-river HPPs availing with several large and one small gen-unit for releasing guaranteed discharge, as well as multi-unit HPPs during the course of refurbishment/uprating. The optimization model is able to cope with various technical constraints, i.e. boundaries of turbines’ exploitation ranges, as well as total spinning reserve and manoeuvrability of load variations of the active gen-units of HPP. A Case Study of Vlasinske HPPs is presented. Findings show that for the analysed asymmetric HPPs energy generation over longterm periods can be increased for over 3%, as well as the revenues of the owner companies.
