Research on situation assessment of active distribution networks considering cyberattacks

With the rapid development of integrated energy system, large-scale and high-permeability access distributed generations (DGs) is making distribution networks develop into active (ADNs). The increased complexity ADNs also increases vulnerabilities for cyberattacks. It a new challenge how to evaluate situation an ADN so as support decision-making grid control policies in condition cyberattacks probably occur. Hence, this paper, we proposed method assessment considering This aggregated by two parts. 1) An index system presented, which includes indexes DGs stability, security risk along with traditional safety indexes. 2) entropy weight used assign weights each index, taking normal operation status reference scenario, operating based on grey correlation analysis method. Finally, order verify effectiveness method, 12 attack scenarios are established from three categories: attacks DGs, controllable loads both them, ADN, case IEEE 33-node standard evaluated under scenario.
