Abstract

Considering the uncertainty and the river flow fluctuations, controlling the reliability of hydropower energy production in competition with other energy production technologies is of considerable importance. Afzali et al. [1] have generalized a simulation model based on reliability (RBS) in single-reservoir hydropower systems to a multiple reservoir RBS model. Simulation of hydropower multi-reservoir system operations have been considered in the present study by using MODSIM model with control on reliability of the system energy yield. MODSIM, as a river basin decision support system, by itself have no ability to effect directly on amount of energy production target to be met at different levels of reliability [2]. By extending MODSIM to MODSIMP, an energy demand node and implementing hydropower standard operating policy (HSOP) will be integrated. This combination made possibility that it go through successive solution of network flow optimization algorithms in each time period of the MODSIM simulation model. This has been done by adding control commands in custom coding environment of the MODSIM8.1 to MATLAB software programmed. The model development and verification procedure has been started from sorting out a simple single-reservoir single-period example problem and then extended to multi-reservoir multi-period models. The results which obtained from application of the developed MODSIMP model to Khersan multi-reservoir hydropower system as a real case study, shows its advantage in terms of computational efficiency and thus its capability of reliability-based simulation operation of multi-reservoir hydropower systems.
