An Analytical Method of Constructing Best-mixed Power Generation Systems Reflecting Public Preference

摘要

An investigation of energy consumer's preference for the power generation was performed. It was found that most consumers gave their preference to a value 'social acceptability' and to 'environmental effect' in constructing the energy system. An analytical method to evaluate the best-mixed power generation system to meet the consumer's preference was developed. It was applied to evaluate each best-mixed system meeting with a preference of each consumer. The resulting best-mixed system was largely composed of the natural gas fired system and the hydraulic power generation system. And the other powers with disadvantages in terms of the 'social acceptability' and/or 'environmental effect' were hardly introduced. The duality theorem allowed us to evaluate the marginal cost of consumers' preference. The 'social acceptability' yielded the highest marginal cost, and the 'environmental effect' was the next.
