Study on generation expansion planning evaluation method based on envelope optimization model

Participants involved in power generation construction were incomplete information and decision-making with bounded rational. Their motivations and behaviours may deviate from environment-friendly and social-welfare generation expansion planning. This paper proposes an envelope optimization model, which aims to meet the goals of minimizing the amount of abandoned water and maximizing the proportion of non-fossil power generation. And it presents a method for evaluating a certain generation expansion planning scheme quantitatively by using this model to calculate non-fossil power sources proportion and abandoned water electricity indicators. Finally, this evaluation method is proved by a regional power system’s generation expansion planning scheme example. The generation expansion planning evaluation method presented in this paper is flexible and practical, which is conducive to guiding and evaluating short-term and long-term regional power development schemes.
