“…In order to minimize the environmental impact and financial investments those hydro generators may be built on existing weirs, dams and other lateral structures and become a run-off-the-river power plants. Therefore in future not only the role of small scale hydroelectricity may increase in Poland but in some cases it will play crucial role in smoothing and balancing inherently variable energy generation coming from photovoltaics and wind turbines [11]. Hence it will be a necessity for a power grid operator to possess knowledge on future VRE energy generation capabilities.…”

Abstract. Hydroelectricity is generally perceived as a stable and predictable power source. However ROR power plant without reservoir energy output is mainly driven by changing flow rate. This study applies artificial neural networks to create flow rate forecasts with one hour lead time. Forecasting models were built for Nysa Kłodzka catchment which possesses significant potential for new hydropower plants development as well as leads to frequent floods. The best of the obtained model gives satisfactory results both in terms of root mean square error (0.6379 m 3 /s) as well as Nash-Sutcliffe performance indicator (0.9978). Obtained results were compared with currently used forecasting models and were proven to be superior.

“…E.g., [10] shows development of reservoir level over the years and hydro power production over the years dependent of some increase in cross-border capacities. However, one of the main conclusions in [9] was that few of the studies include both wind and solar resources and with shares which can be expected in a perspective to 2050. Thus, conclusions about operational patterns may be different with higher shares of variable resources in the power system.…”

“…This paper is based on the same methodology as [15], but focuses on other results. While [15] focuses on the impacts for the European power system and in particular the power prices, this paper is about the impacts on the Norwegian system. It aims to show how increases of capacity influences the system in terms of changes in production pattern and reservoir operation.…”

“…Reference [9] identified state-of-the-art related to use of Nordic hydropower for balancing and storage of variable wind and solar based power production in the future Northern European system. The paper focused on the following topics: (1) the need for balancing and storage; (2) possible further development of the Nordic power system; (3) consequences of different market solutions; (4) changes in operations of the Nordic system.…”

Future power production in Europe is expected to include large shares of variable wind and solar power production. Norway, with approximately half of the hydropower reservoir capacity in Europe, can contribute to balance the variability. The aim of this paper is to assess how such a role may impact the Norwegian hydropower system in terms of production pattern of the plants, changes in reservoir level and water values. The study uses a stochastic optimization and simulation model and analyses an eHighway2050 scenario combined with increases in the hydropower production capacities in Norway. The capacity increases from ca. 31 GW in the present system to 42 and 50 GW respectively. The study uses 75 years with stochastic wind, solar radiation, temperature and inflow data. The results show that the hydropower system is able to partly balance the variable production and significantly reduce the power prices for the analyzed case. The paper shows that some of the power plants utilize their increased capacity, while other plants do not due to hydrological constraints and model limitations. The paper discusses how the modelling can be further improved in order to quantify more of the potential impacts on the future power system.
