Extended multi-objective firefly algorithm for hydropower energy generation
Classical methods have severe limitations (such as being trapped in local optima, and the curse of dimensionality) to solve optimization problems. Evolutionary or meta-heuristic algorithms are currently favored as the tools of choice for tackling such complex non-linear reservoir operations. This paper evaluates the performance of an extended multi-objective developed firefly algorithm ...

Capacity optimization of hydropower storage projects using particle swarm optimization algorithm
A mixed integer optimization model is formulated for capacity optimization of a hydropower storage project with control on reliability of meeting the project's firm energy yield. Particle swarm optimization (PSO) is used as the optimization algorithm, in which the method of sequential streamflow routing is called for objective function evaluations. Two types of problems are studied. The first one ...

Large-scale hydropower system optimization using dynamic programming and object-oriented programming: the case of the Northeast China Power Grid
This paper examines long-term optimal operation using dynamic programming for a large hydropower system of 10 reservoirs in Northeast China. Besides considering flow and hydraulic head, the optimization explicitly includes time-varying electricity market prices to maximize benefit. Two techniques are used to reduce the ‘curse of dimensionality’ of dynamic programming with many ...

Developing reservoir operational decision rule by genetic programming
The reservoir operational decision rule is an equation that can balance reservoir system parameters in each period by considering previous experiences of the system. That equation includes variables such as inflow, volume storage and released water from the reservoir that are commonly related to each other by some constant coefficients in predefined linear and nonlinear patterns. Although ...

How to plan hydropower stations for the future
The hydropower plants of tomorrow won’t only produce energy. Constructing dams will also provide new drinking water sources, irrigation for crops, and new waterways for transport. In the words of most of the scientists here at World Water Week in Stockholm, Sweden, they will be ‘multipurpose’. This means that each plant design will be a one-off. And, more importantly, each will ...
