AVIEW | HYDROSIM is a software that provides operation regime optimizations for reservoir HPP operations and investments. With in-house developed algorithms, various flow and precipitation data is used for the stochastic hydrology forecasts. By using these stochastic forecasts and plant constraints, operation optimizations are carried out for hydropower plants in a cascade basin. AVIEW | HYDROSIM, supports the decision making process for water retention or generation and also ensures water usage with the highest utilization for the HPPs in the same basin. Moreover, HydroSim helps investors for the establishment of financial models and provides optimum pricing strategies during the operation period and thus conducts income and expense simulations for the Day Ahead and Balancing Market.
