Framework for the Economic Analysis of Hybrid Systems Based on Exergy Consumption.

摘要

Beginning with an overview of the evolving dynamic behavior of the electricity market, this report presents an approach to better inform energy users within that market to enable them to make sound decisions. These users are an essential component in providing a damping capability to the nationwide electric grid as the energy generation systems become more diverse and intermittent. This work includes a qualitative analysis of the impact of uncertainty, both in the demand and supply side. An introduction to investment analysis methodologies based on discounted cash flow is then provided, followed by an illustration and application of exergonomic principles to cost accounting of plant components used in cash flow analysis. Exergonomics is a new approach to the investment analysis of proposed systems, where the cost driver for product stream allocation is exergy utilization. Thus, through exergonomics, the opportunity cost generated due to incomplete usage of potential work (exergy), is minimized, or perhaps even eliminated.
