Research on the Development and Index System of Smart Distribution Network in China in the Future

Abstract

The goal of "Carbon peaks & Carbon neutrality" is not only the requirement of ecological civilization construction, but also a clear requirement for high-quality economic development. In order to achieve the goal of "Carbon peaks & Carbon neutrality", China is facing the simultaneous transformation and upgrading of economic structure and energy structure. With the advance of China's modernization, the power grid will continue to play the role of "bridge" and "link", and China's future distribution network will become the key to development. Building a smart distribution network is the demand of building a new power network, and also the requirement of transformation and upgrading to the energy Internet. This paper analyzed the main driving factors and paths of distribution network evolution and development in developed countries, put forward the functional orientation and main characteristics of China's future smart distribution network development based on the main needs of regional economic development, rural revitalization, Carbon peaks & Carbon neutrality and new power network in China's future distribution network development, and designed the index system of future smart distribution network based on its main characteristics, so as to guide the future development direction of distribution network.

Comprehensive Evaluation of Distributed PV Grid-Connected Based on Combined Weighting Weights and TOPSIS-RSR Method

“…The overall trend of the weight values of the indicators in reference [17] and this paper is closer, and the confidence level is higher. However, in this paper, in the dimension of reliability, the weights of most of the secondary indicators are generally higher than those in reference [17], which is in line with the higher requirements for reliability of modernized distribution grids under China's national conditions; In addition, in the two dimensions of absorptive capacity and economy, most of the secondary indicators in this paper are similarly weighted higher than those in reference [17], which is in line with the main development direction of the distribution network in the new era under China's national conditions: to improve the distribution network's ability to consume distributed power sources and to reduce the operating costs of the distribution network [35]. This shows the rationality and correctness of the combination assignment method proposed in this paper.…”
