Research on Evaluation System of Power Control Architecture of Active Distribution Grid
Large quantity of application of distributed power source and all types of soft load determined that the control architecture of active distribution grid has to face the duty of assuring dynamic equilibrium of system energy and improving power quality, so it is urgent to build a comprehensive evaluation system, which has to be objective, fair, accurate and effective, for control architecture of active distribution grid. Main factors that could impact the power control of active distribution grid were extracted and comprehensive evaluation system was built in this article, according to the features of centralized, centralized-distributed and distributed control architectures. Combined weights that objectively evaluated were obtained by adjusting subjective weights which were determined by analytic hierarchy process (AHP) using entropy weight. Comprehensive evaluation was conducted by applying multi-level gray relational analysis (MGRA). Using the demonstration project of district power center from XJ Corporations as an example, a comprehensive evaluation was conducted for three types of power control architectures and final evaluation results were analyzed, so that the rationality and feasibility of methods and systems were verified.
