Power Generation Simulation of a Hydropower Reservoir System Using System Dynamics: Case Study of Karoon Reservoir System

AbstractThe system dynamics approach is an object-oriented simulation method based on feedback loops, flow diagrams, and flow and state variables, which can be used in the development of a water system’s operational policies and water-resource management. In reservoir operation simulations, there are iterative procedures (feedback loops) due to the dependency of reservoir release on both initial and final reservoir storage. System dynamics can successfully satisfy this need. Given the complex implicit and nonlinear relationships that exist in hydropower reservoirs, the system dynamics approach can be efficient in the planning and management of those reservoirs. This paper develops a system-dynamics simulation model using Vensim for the operation of a hydropower reservoir system (Khersan 1, Karoon 4, and Karoon 3) that is located in series and in parallel in the Karoon river basin, Iran. Steps of the model design include definition of decision variables, formulation of model, and method of solution to comp...
