Development of the software “Water and energy balances calculations for Angara and Yenisei series of HPS”

Abstract

The structure of Siberian power system installed capacity is characterized by significant amount of hydro power stations (HPS). There is a necessity to make long-term forecasts of Angara and Yenisei series of HPS mode with constant updating for the shortterm planning. Moreover, with modern IT technologies there is no difficulties to create an algorithm for such calculations. Nevertheless, the process of mathematical program description for calculations is rather complicated due to various limitations of water usage. Statistical database that is in use influences sufficiently on reliability of calculated water and energy balances. The software, which is currently in use for Angara and Yenisei series of HPS calculations of mode, does not provide the needed level of calculations variability and reliability entirely. While comparing results of simulations with statistical data of HPS mode, taking into consideration the necessity to plan HPS mode for Siberian power system, the decision was made - to develop proper software “Water and energy balances calculations for Angara and Yenisei series of HPS”. It takes into account HPS interference within series. Furthermore, there is an opportunity to calculate different scenarios of HPS operations. For the current moment the first version of the program is done, according to technical specification.
