Abstract
For multireservoir systems with hydropower purposes, the best strategy of joint
operation is to firstly release water from the reservoir with the higher
hydropower efficiency in order to achieve the highest benefits of the whole
system. Considering the scarcity of water resources however, the operational
practice is to follow a proper set of rule curves so as not only to reduce the water
shortage amount and duration for downstream water demand but also to enhance
the hydropower efficiency. Therefore, an operational model coupled with
simulation and genetic algorithms is presented in this paper to overcome the
difficulty with nonlinear and multiple parameters. In this paper, the joint
operation of Shihmen and Festui Reservoirs in northern Taiwan was chosen for
the case study. The study results indicate that the optimal operating rule curves
of the parallel multireservoir system can achieve the highest hydropower benefit
and meet the designed firm yield for water supply simultaneously.
Keywords: parallel multireservoir systems, soft optimization, rule curve-based
reservoir operation, hydropower.
1 Introduction
Numerous studies address the problem of defining optimum operation rules for
reservoir systems with multiple purposes. (Nalbantis and Koutsoyiannis [11],
1997; Belaineh et al., 1999 [1]; Lund and Guzman, 1999 [9]; Oscar and Eduardo,
2005 [12].) However, considering scarcity of water resources for water supply,
the operation practice is to follow a proper set of rule curves so as not only to
