Review on Research of Regional Integrated Energy System Planning

As the physical carrier of Energy Internet, regional integrated energy system (RIES) has become an important role for improving comprehensive energy utilization efficiency, renewable energy consumption, energy supply reliability, energy saving and emission reduction. The planning of RIES encounters many challenges, such as industry boundaries, policies, regional differences and techniques. In this paper, the key problems of RIES planning are discussed including multi-energy coupling, load forecasting, technical economy and optimization modelling. The domestic and foreign relative researches are summarized systematically. Based on the latest research progress, a universal energy flow model, planning model and solution process covering the source, network, load and storage of district integrated energy system are summarized, and the future research directions are prospected. © 2019 Automation of Electric Power Systems Press.
