Diversified Reliability Improvement Measures and Cost-Benefit Analysis of New Power Distribution System Based on Distributed Technology

As an important part of the energy supply chain, the power distribution system is facing the problem of increasing energy demand and complex energy supply pattern. In order to solve these problems, this paper studies a new type of distribution system based on distributed technology, and conducts a cost-benefit analysis of the new type of distribution system through discounted cash flow and life cycle cost models. The results of the study show that the new distribution system has a positive net present value and an internal rate of return of 17%, which indicates that the system is economically viable. Through the analysis of economic benefits, this paper proposes countermeasures such as multi-source power supply, energy storage technology, microgrid and intelligent network connection, automatic monitoring and fault detection, backup equipment and redundancy, and emergency planning and drills, which can effectively improve the reliability of the system.
