PowerSimmTM Hydro Manager

PowerSimmTM Hydro Manager integrates both physical operations and hydro specific portfolio constraints in a single analytic framework. Ascend's model utilizes an advanced stochastic simulation framework to analyze & optimize the operations of cascading systems, pumped storage, run of river, and peaking assets.

Get the insight you need to make the right decisions.

PowerSimmTM Hydro Manager allows individual turbine-level efficiency curves and constraints to be specified as functions of reservoir levels.  This detailed model specification results in hydro simulations that accurately reflect true operating regimes and provide insight into the value and trade-off of generation and ancillary services.

PowerSimmTM Hydro Manager's advanced solver applies approximate dynamic programming to capture meaningful uncertainty in future stream flows and load conditions.


This uncertainty can be used to assess the likelihood of various future regimes and to form a better picture of expected and potential future revenue generated by the hydro asset.
