| Electric grid expansion projects demand for significant investment while the amount of funds is limited. Because electric grid projects have the characteristics of public goods, it is difficult to measure the effectiveness of a single project. This results in a lack of reasonable standards to evaluate the projects and the difficulty to determine the optimal portfolio of projects subject to the capital constraints.So it is urgent for electric enterprise to study a scientific and practical method to investment evaluation. First of all,this paper analyse the basic theory of benefit assessment and investment portfolio optimization, on the analysis of typical cases in the domestic and at the a-board, Investment Management mechanism has been studied. Pre-Evaluation system of grid project is established through analyzing factors of investment decision, and this article develops an optimal portfolio model for electric grid projects taking into account the social benefits of the projects and power system reliability. The genetic algorithm is proved suitable for the proposed model through comparison of different algorithms.This article also analyse the investment benefit assessment and assessment Mechanism. An illustrative case study is analyzed empirically at the end of this paper. |
