The credible capacity and the credible capacity of energy storage for calculating distributed generation resource first realize cleaning in conjunction with the operating condition of power grid
The energy accesses.
2, soft control strategy of the spatial load forecasting cloud platform to controllable burden；
First all controllable burdens are classified, are divided into insignificant load and important load, insignificant load is controlled
System.
Insignificant load is that the load not impacted to user's production and living, such as air-conditioning, hot water are interrupted in supply of electric power
Device, refrigerator etc., in control, the insignificant load rejection time is shorter, once send power recovery outside, you can restore, the short time
The production and living of user will not be impacted by interrupting this type load, but very big to the contribution of power grid, while can pass through market
Policy guides.
Important load is that the load impacted to user's production and living is interrupted in supply of electric power.
Spatial load forecasting cloud platform includes micro-control switch control and Precise control to the flexible control pattern of controllable burden.
Micro-control switch controls, that is, directly controls the micro-control switch division of relevant device, mainly for temperature control load, such as,
Control electrical appliance etc. of breaking up the family；The long-range folding of micro-control switch be unable to do without remote control plug-in part technology, is remotely controlled plug-in part technology feature and realization side
