Study of Coal-to-Electricity Project influences on electric distribution systems in North Hebei Province in China

Abstract

Abstract Coal-to-Electricity Projects are being carried on in North China in order to reduce air pollution. These projects have brought many challenges to present electric distribution networks. Therefore, this paper focuses on how the practical electric distribution systems act facing a large quantity of electric heating integration and how to improve the behaviours. Field researches are conducted covering all cities in North Hebei Province. The current problems in planning, operation and investment of the power distribution networks supporting Coal-to-Electricity Projects are founded, and the reasons are analysed. The suggestions on the above three aspects are put forward accordingly. Case study on the distribution system in Xianghe County is conducted, and the effectiveness of the proposed approaches are verified. This study may give reference on Coal-to-Electricity related electric distribution work for other places and for the future, and also guide practical planning, operation and investment of power distribution systems on special issues.
