Characteristic analysis for summer weather sensitive loads of power grids;

With improvement of people s living standards,the proportion of weather sensitive loads for cooling and heating purposes is growing larger and larger and weather is presenting ever greater influence on the loads of the power grid.

The methods research of monthly sensitive load forecasting

The exposed areas of voltage sags,which could provide the basic rules for strengthening the power network,selecting the optimum operation mode,and selecting the position connecting the sensitive load with the distribution system,can be estimated by utilizing the fault simulation method.

The key of voltage sag sensitivity assessment of sensitive equipments consists in the determination of random distribution regularity of voltage tolerate curve.

Based on physical characteristics, existing stochastic estimation methods of equipment sensitivity to voltage sag use subjective probability models to express the probability distribution of voltage tolerance curve (VTC) of equipment in the uncertain region.
