Influencing Factors of Pumped Storage Power Stations from the Perspective of Multi-Energy Complementarity: A Case Study of Liaoning Qingyuan Pumped Storage Power Station

Taking Qingyuan Pumped Storage Power Station, Fushun City, Liaoning Province, as a case study, this paper proposes an operations management framework for pumped storage power stations from the perspective of multi-energy complementarity. Through the design of an operations management questionnaire, along with on-site inspections and questionnaire distribution, the influencing factors of operations management of pumped storage power stations from a multi-energy complementarity viewpoint was surveyed. Using mean analysis, the main issues in the operations management of pumped storage power stations from a multi-energy complementarity perspective are the determination of electricity pricing mechanisms, allocation of responsibilities and rights among stakeholders, and the lack of application of digital management technologies. By employing system clustering methods, the key influencing factors of the operations management of pumped storage power stations from the perspective of multi-energy complementarity are divided into six categories: policy support, power market demand, advanced technology and equipment, incentive mechanisms and profitability, intelligent management of multi-energy complementarity, and mutually-beneficial and win-win cooperation between source-grid-load-storage. Based on the analysis of the current state of key management elements, a management system for pumped storage power stations from the perspective of multi-energy complementarity is proposed, as well as an organizational structure for stakeholders of pumped storage power stations. Based on the above, strategies for stakeholder management, adjustment of the power grid and integrated management of new energy consumption for pumped storage power stations, and strategies for building an integrated smart grid for source-grid-load-storage are proposed. © 2024 Peking University.
