Substitution Study for Cost Effective Hybrid Power System using Power Pinch Analysis

Issues with the imbalance of supply and demand as well as the increasing emission
of carbon dioxide have led to the advancement of other alternatives to generate power
based on renewable energy (RE). However, implementing RE for power generation in
hybrid power system (HPS) is a challenging task. The technology of RE is known to be
upscale and RE resources especially solar and wind are highly-dependent on weather and
climate conditions. The objective of this research is to design a cost-effective HPS using
Power Pinch Analysis and the substitution strategy from Systematic Hierarchical
Approach for Cost-Screening Technique (SHARPS). Modified Storage Cascade Table
(SCT) which is one of Power Pinch Analysis method was constructed to find the minimum
electricity target which was used to analyse the investment cost per saving of RE
generation technologies involved.
