Abstract

ABSTRACT： The implementation of microgrid is an effective way to promote new energy consumption, and is significant to support low-carbon economy development. The planning section is important to ensure the secure, reliable and economical operation of microgrid. Based on the latest researches and progress at home and abroad, the technical features are summarized and remarked as well as research status of microgrid planning on topics of uncertainty dealing, multi-objective planning, planning-operation coordinated modeling and the solving algorithms in this paper. The viewpoint and emphasis of coordinated microgrid-distribution planning and the technical issues that need to be addressed are put forward to cope with the impact of large-scale microgrid participation on distribution planning. Besides, strategies of voltage-grading and district-dividing planning and modular design are presented in order to solve the complex microgrid planning problem, which helps to reduce the design difficulty, construction cost and improve construction efficiency.
