A Real Option based Approach for Generation Investment Decision-Making and Generation Capacity Adequacy Analysis

摘要

The deregulation of power industry brings not only more uncertainties and risks for investors in making generation investment decisions, but also a new challenge to governments or regulators for designing an effective market mechanism to ensure adequate generation capacity and hence reliable electricity supply. Provided that the load growth uncertainty is the major source of uncertainty, a new methodological framework for generation investment decision-making is presented based on the well-developed real option approach (ROA), with competition for generation investment from other investors taken into account A mathematical model is developed and a solution is presented for this purpose. Finally, the proposed method is illustrated by a numerical example. The effects of different market mechanisms on generation investment incentives and hence the generation capacity adequacy are also investigated in a quantitative way.
