Guys PLEASE .... I don't want to spend all my time negatively saying why things can't be done, I'm asking you for detailed electical input not a brainstorming session on what you would do if you were me. I've said it a few times - I don't want to discuss grid capacity expansion here.
Micro Hydro projects are 'run of the water' - drawing from a wier rather than a dam - so no hydroelectic pumping. As I said before - the technology (including indigenous turbine manufacture) is not a problem. It is a mature system with national standards. Extensive hyrdrology studies are carried out before funding is approved and the maximum capacity of the stream is tapped. I will look into the financial feasibility of 'over-drawing' this resource for peak periods but in the changing climate/deforestation it may lead to a largely redundant and expensive extra turbine. Can we leave this point here. Distribution is the project area.
In-home storage with a view to temporary power increase - with or without inverters - is the brief. If village capacity is subsequently increased, great, the distribution system is still valid.
If synchronous inverters are a no-go, does anyone have any other suggestions as to how a 400W supply can be upped to a 1000W supply temporarily ?
