Analysis of Key Constraining Factors on Load Control for Power Grid Companies from the Perspective of Industrial Chain Sustainability

The rapid decline in the costs of wind and solar power is accelerating the low-carbon transition of the power system. However, with the advancement of new-type power system construction, load control for power grid companies is facing multiple constraints. Based on the actual operational context of power grid companies in China, in this paper we systematically analyze the key constraining factors on load control from an industrial chain perspective. Firstly, we identify the constraining factors which affect the load control of power grid companies from the industrial chain viewpoint. Then, we propose an analytical method for key constraining factors based on a novel interactive group Decision Making Trial and Evaluation Laboratory (DEMATEL) approach. Finally, using Yunnan Power Grid Company in China as a case study, we identify specific constraining factors, including power generation costs, electricity pricing policies, distribution equipment capacity, and the level of grid intelligence, thereby providing a theoretical basis and practical pathways for enhancing the effectiveness of load control.
