Investment Optimization Model for Distribution Networks Projects With Risk and Efficiency Constraints

A Learning-to-Rank-Based Investment Portfolio Optimization Framework for Smart Grid Planning

“…Moreover, it is necessary to fully consider the factors of the current situation and future progress of the power grid in different provinces. It is also complicated and demanding work with a large amount of data, workload, and high technical requirements (Liu et al, 2020).…”

“…Most of the existing investment portfolio optimization strategies are from the perspective of problem-oriented research, based on the known investment demands and investment capabilities of the enterprise, referring to the previous investment allocation, to allocate the investment scale and investment structure of each unit (Peng and Zhang, 2015;Li et al, 2021). The objective function and constraints are not considered enough comprehensive and systematic, and model boundary conditions and project priority ranking rely mainly on expert experience to make subjective decisions, lacking the recognition and consideration of objective factors (Guelpa et al, 2019;Liu et al, 2020;Ma et al, 2020).…”

“…Power grid investment decision-making is a complex process that needs to consider the objectives of the economic, social, and security benefits and meet the constraints of capital investment, project construction time sequence, and power demand (Peng and Zhang, 2015;Liu et al, 2020). It is difficult to reproduce this process with a simple end-to-end machine learning method.…”

“…The investment portfolio optimization objective of the power grid infrastructure project is to minimize the comprehensive benefits (Peng and Zhang, 2015;Liu et al, 2020;Ma et al, 2020). The traditional optimization decisionmaking method is usually based on the investment performance evaluation index system to score the projects.…”

Research on Investment Strategy and Evaluation Mechanism of Power Enterprises Considering Local Development Characteristics

“…It only analyzes the impact of power and can not judge the investment decision comprehensively. Reference [4] proposed an accurate investment project selection model considering risk measurement and designed a two-tier index system for investment benefit evaluation of distribution network projects. However, it lacks the analysis of profit growth after investment, so it is impossible to accurately judge which projects are more worthy of investment.…”
