A Smart Grid Planning Method with Coal-to-electricity Based on Multifactor Adaptability

Abstract

Abstract In order to reduce coal pollution and improve air quality in winter, many cities in northern China began to promote coal-to-electricity, and a series of policy subsidies were released accordingly. With the implementation of coal-to-electricity, the characteristics of power network has been changed significantly and the traditional planning method is no longer applicable. To meet the needs of coal-to-electricity engineering, a smart grid planning method with coal-to-electricity based on multifactor adaptability is proposed in this paper. First, the coal-to-electricity load characteristics is analysed, and typical parameters is proposed based on the actual operation data, which considers the impacts of different types of equipment and breaks through the modelling difficulties of coal-to-electricity characteristics. Then, a smart grid planning method with coal-to-electricity based on multifactor adaptability is set up, which combines the influence of transmission capacity for each equipment, the investment capacity for each participant, and the social acceptance of the electricity price. Based on this model, the technical, economic, and environmental benefits of coal-to-electricity modification are coordinated. The application shows that the proposed method is concise and effective and provides useful suggestions for determining the coal-to-electricity scale, network planning and compensation policy, which supports the implementation of coal-to-electricity.
