Research on Paying Rules and Distributions of Generation Companies Under Different Trading Rules Jianping Wang, Tao Zhang and Xianjia Wang
Abstract In order to speed up the process of China’s electricity market, and promote the development of electricity industry, this paper tries to introduce different trading rules to improve power market transaction. It focuses on the regional electricity market within power grid and electricity trading rules in a theoretical study and discussion which are based on three different conditions, namely, the discriminatory trading rules, uniform price trading rules, and separated uniform price trading rules. Power grid provides different allocation rules and payment rules to the generation companies under these trading rules. In addition, numerical example will further explain the different trading rules in the specific power distribution method and payment method.

72.1 Introduction As the development of power industry in China, promoting vigorously the construction of regional electricity market became a common view. Based on these advanced conditions, studying on the trading rules between power grid and generation companies also receives much more attention, which, at the same time, is J. Wang (&) T.

of great significance to the building and perfection of the regional power market. However, different trading rules will lead to different bidding strategies of generation companies. So the designs of trading rules should be aimed at the specific characteristics of the target market so as to realize its maneuverability. Meanwhile, the designs should reflect the characteristics of the goods or services and be well tested in constant practice and amendments. Finally, these designs should continually become more and more complete and reasonable. In the current study on the regional electricity market trading rules, the literature [1] proposes a new transaction scheduling method of considering network constraints. This method will resolve the problems of coordination existing in the multilevel electricity market by introducing generating contribution factors and load extracting factors. At the same time, it builds mathematical models of trading planning which are made in the regional power market by adopting transaction matrix methods. According to the buy electricity directly for large users and the description of bidding and auctioning trading rules [2]. Literature proposes
