Concurrent Optimization of Component Capital Cost and Expected O&M

Description

Concentrating Solar Power (CSP) technologies combine heat generation from a field of reflective
mirrors with a thermodynamic power conversion cycle, typically using an expansion-turbine
loop. Among the four major CSP technologies – parabolic trough, linear Fresnel, dish Stirling,
and power tower – the lattermost represents the area of primary attention for efficiency
improvement and cost reduction. The collector system is typically the most costly CSP
subsystem and hence warrants the most comprehensive analysis for the design cost versus O&M
tradeoff, although this analysis must be undertaken in light of the other interrelated subsystems.
CSP solar fields consist of thousands of parallel components (i.e., heliostats), so optimization of
this subsystem differs from how one addresses a single point of failure, such as boiler or turbogenerator.
This presents a unique opportunity for CSP: Because of the large number of parallel
components, the state of the solar field, as the heliostats degrade over time, is governed by large
sample size statistics, rather than a simple up-down state.
