In this paper, a framework for WAMS communication system security assessment is presented. Firstly, it divided the communication systems of WAMS into several subcomponents according to ISO/IEC 17799, and then associated the assets' property by the Architecture Theory Diagrams (ATD). Secondly, the AHP is introduced to build the assessment hierarchy and distribute the index weight. At last, the data...
Based on dynamic programming method, the unified planning mathematical model of multi-voltage substation is established. The model takes the voltage levels as phases, the location and sizing of new stations as decision-making, the power supply scope as state, and the annual cost of multi-voltage levels overall investment as objective function. In the paper, for locating and sizing of 110 substations,...
In this paper, based on Centralized Distributed model, a study method of reliability of WAMS is presented. The whole WAMS system is divided into two sub-systems: Monitor Center System and Data Acquisition System. The Communication System is also modeled as an auxiliary evaluation system. According to the Markov condition, the Monitor Center System establishes the Kolomogorov equation, sets the invalidation...
Studying the optimal subsection of distribution networks feeders, a subsection scheme synthesizing load and the length of subsections is presented. Hierarchical data envelopment analysis (DEA) method is proposed for multi-objective evaluation of subsection schemes. First, the scientific assessment system is established by using the analytic hierarchy process (AHP) and the weights of assessment criteria...
