An integrated power system model including both primary and secondary equipments is required by the integrated information platform for electric utilities to meet the actual demands of a variety of applications based on relay information. The grid model currently used by utilities contains basically only the primary model to the neglect of the secondary model. Following an analysis of the inadequacy of the protection model in the current common information model (CIM), a CIM extended general protection model is presented, which is comprehensive, scalable and capable of shielding the differences between the protection devices of different vendors. The protection model has been applied in the decision-making system of China Southern Power Grid. Reults show that the proposed general protection model is efficient and feasible. © 2012 State Grid Electric Power Research Institute Press.

With the large-scale wind power connected into the power systems, the influence of wind farms penetration should be considered in power system dispatch. A clean development of the power industry was required because of the increasingly serious global climate change and the strategy of sustainable development of human society. Based on the optimal dispatch in traditional power system, the concept of "energy-environmental efficiency" was introduced to modify the optimal dispatch model in wind power integrated system, and the multi-objective optimal dispatch model was proposed on the basis of comprehensively considering the minimum of the resource consumption, the best energy-environmental efficiency and the highest system stability. A hybrid particle swarm and tabu search optimization algorithm with fuzzy technology was presented to solve the optimization model. Experimental results show that the proposed optimization dispatch model is reasonable and the algorithm is feasible. © 2011 Chinese Society for Electrical Engineering.
