An approach to design and implement the control function of LD (Ladder Diagram) in the hydropower simulation system based on all paths searching algorithm is proposed in this paper. LD is widely used as a programming language for PLC (Programmable Logic Controller), but it doesn’t be executed automatically in the hydropower simulation system which is a software system, and there is no compiler ...

Energy transition is a major structural change in the whole social system, and energy system must be changed globally to replace fossil fuels. Hydropower one of largest sources renewable world. However, owing construction hydropower projects, involuntary resettlers are suffering from being far away their native land, losing land cultivated for generations houses they live in, relationship netwo...

In this paper, a many-objective optimization algorithm was developed using SPEA2 for system of four reservoirs in the Karun basin, including hydropower, municipal and industrial, agricultural, environmental objectives. For purpose, 53 years available data, hedging rules were two modes: with without applying fuzzy logic. used to optimize coefficients first 43 data last 10 test optimized rule cur...

The paper describes and analyses a hydropower system based on siphons in which the pressure of low-head water is converted into air pressure. The analysis suggests that, with careful design of the  ow passages to minimize losses, air-pumping efŽ ciencies of 70 per cent or more should be achievable; the overall efŽ ciency of the hydropower system should be better than 60 per cent. Although such...

Theoretical hydropower operation rules are derived and discussed for reservoirs in parallel, in series, and single reservoirs for cases where reservoirs typically refill before they empty and for parallel reservoirs when reservoirs are expected to draw down to empty. These hydropower rules offer a simplified economic basis for allocating storage and energy in multireservoir hydropower systems. ...

The MINERVE project was initiated for flood management in the Upper Rhone river basin. Its first goal is the prediction of floods. The second one is the optimum management of the complex system of hydropower plants located in the basin in order to diminish the peak discharge in the Rhone River and its tributaries. The MINERVE Interactive Decision Support (MINDS) proposes turbine and bottom outl...
