| Abstract | There has been increasing interest in quantities methods for
reliability evaluation in power systems to obtain a better balance
between cost and reliability. The present study analyses the
static reliability evaluation of a largely hydro based hydro
thermal power system.
Hydro energy availability of a hydro plant is limited by the
stochasticity in streamflows to the reservoir. In a hydrothermal
power system, thermal plants can be used to back up the hydro
plant conserving more water, which wi11 enhance the system
reliability. Therefore, reliability is heavily dependent on the
operating policy.
In this study, a stochastic dynamic programming approach is
developed to quantify the above relationships. Optimal release
policies are found for various levels of reliability for a
simplified hydro thermal system. Derived policies are tested by a
28 year simulation.
This implication as connected with optimal capacity expansion
of a hydro thermal power system is investigated with the
developed optimization - simulation routine and results are
compared with those obtained from a simplified conventional
expansion mode1 . |
