Abstract

Moving towards smart distribution power system network, the control ability and the management strategy are the key issues. According to both issues, this study is dedicated on the electricity energy trading in distribution network. This research topic will empower the distribution network in the part of management strategy. Creating the study system, the interconnected microgrids network is selected, because the microgrid has capability to be functioned as a generation and a load. In order to analyze the electricity energy trading strategy, the network operation structure has to be divided based on the operation function, i.e. business layer, information layer and physical layer. This separation is aimed to differentiate the economic operation and the technical operation. The information layer takes in charge of transferring the data between both operations. The important exchanging data are clarified in this study. Regarding the decision-making process in economic operation, this research proposed the fuzzy logic with arithmetic weight method and the noncooperative game theory. Both decision-making processes are applied into cooperative market and competitive market in order to compare and figure out the character of the decision-making method. All in all, the proposed decision-making method is able to imply for energy trading analysis and revenue evaluation.
