Saleem,

This type of thing has been done at least a couple of times in GoldSim for a real application as far as I know. It has probably been done more than that. While we don't have an example that does exactly what you need (for 4 hour peaking) but you can start here: Run-of-River Hydroelectric Power Generation. You might also want to review these examples: Great Falls Project Hydropower Operation Management and this one: Hydroelectric Power Revenue Optimization

Can I ask you what strategy you are thinking of to simulate 4 hours peaking? I'm only asking about the basic strategy so I can possibly provide pointers of how you might build this.

Thanks and good luck,

Jason

Jason,

Thanks for your reply and guidance. I have gone through the above mentioned examples. It helped a lot to understand the functioning of GoldSim for reservoir modelling. However, I still need help to setup GoldSim model for my study area as I am trying to adept GoldSim model instead of spreadsheet models or Hec ResSim. Let me explain my modelling scenario below

1. A hydropower is already designed on a stream ( upstream side) with daily 4 hour peaking. The design discharge is 66 m3/s and 5 m3/s is environmental flow. It has capacity of 1.2 million cubic meter. Daily flow data series is available at the upstream of damsite..

2. A new hydropower is proposed downstream side ( 500 Km2) from this project.  The project will use outflow of upstream project and contribution of flow from the catchment between these projects. It has very small capacity ( 50,000 cubic meter) and design discharge of 66 m3/s and 11 m3/s environmental flow.

3. I need to setup model to determine flow upstream of second hydropower project ( hourly flows) and outflows of 2nd hydropower ( hourly).

Thank you very much

Saleem

Saleem,

This is certainly something you can do in GoldSim. Consider starting off by building the upstream system unless you only want to link to discharge rates that are already calculated. Then, if you can determine when peaking time starts (based on electrical demand or time of day?) then you build the logic to simulate discharges from the downstream dam. There might be feedback between the two dams. For example, if you need to equalize the water levels at each dam by sending more (or less) water down from the top dam. This will require that you have some feedback from the lower dam, back up to the upper dam to trigger changes in the operation. There are multiple things to consider here but you can certainly do this using GoldSim. Can you try building a small prototype then show me what you've done and I can comment?

Thanks,

Jason
