Scale Estimation Model Of Electricity Emergency Goods Reservation And Its Simulation

The power system in case of sudden disasters, in order to control hazards, the size of effective emergency management must be carried out. Emergency management needs a large number of emergency supplies of electricity, however, in the local area and emergency key time within the scope of these is a severe lack of emergency supplies. Therefore, in order to improve the quality and efficiency of emergency management, improve the ability of prevention and treatment of emergency power system, minimize the impact and losses, research on electric power emergency supplies reasonable reserve under the normal mode and reserves, in the need to give full play to the role is very necessary.According to the characteristics of electric power emergency materials, selection of material importance, material scarcity and supplies timeliness indexes, realizes the classification of power emergency supplies; three kinds of storage methods and two reserve subjects are combined to form five kinds of reserves; reserves of the style and grade model compare hierarchical model of reserve eventually established the power of emergency materials.According to the historical data, to determine the power of emergency material demand function and distribution function; in the guarantee of emergency material constraints, with emergency supplies reserve power enterprises expected cost minimization, the agreement enterprises expected profit maximization as the goal and achieve supply chain coordination, respectively construct the reserve body different reserve model in classification the optimal emergency supplies reserve scale and makes the calculation model of electric power enterprise of supply chain coordination optimal compensation amount. For wire and cable does not belong to a single level of material construction widely used material reserve scale calculation model; according to the actual situation of supplies and decentralized, introducing reserve point index, constructed the reserve point reserve scale calculation model. Finally, the introduction of an example, implementation model using VC++ algorithm, to verify feasibility of reserve estimates the size and effectiveness of the model, in order to provide a useful reference for power emergency materials reserve in china.
