Review on optimal planning of new power systems with distributed generations and electric vehicles

Abstract

As distributed generations (DG) and electric vehicles (EV) are widely integrated into power systems, the power network has undergone significant changes in structure, function, and operational characteristics. Therefore, effective management and control of distributed energy sources and EV charging power by power system operators becomes necessary. In this paper, the physical characteristics of new power systems are summarized. The influence of DG and EV connected to power systems on system planning is analyzed. Then, based on the review of the existing planning models, the problems and technical difficulties are reviewed from the aspects of control strategy, power flow calculation, uncertainty processing, network planning, and equipment planning. Considering the problems and challenges, key technologies are presented. Finally, future directions are provided in four aspects, including system interdependence, various EV charging response, system resilience, and planning evaluation.
