The fuse salt energy storage installed capacity of the battery energy storage capacity of system or solar-thermal generating system, energy storage state, energy conversion efficiency, distribution
The factor such as net pressure regulation requirement and Flexible Control mode.And, these influence factors are usually constructed with stochastic uncertainty or obscure not
Definitiveness, or he is that have random and fuzzy uncertainty, is often deposited with random and fuzzy uncertainty event or parameter
?.
Output level due to photovoltaic and solar-thermal generating system has very big because multiple uncertain factors affect
Randomness and ambiguity, for fuzzy uncertainty, to be traditionally analyzed using Fuzzy Analysis and to locate
The information of reason fuzzy uncertainty.But traditional method such as Zadeh fuzzy set or TYPE1 fuzzy set imitation and description are fuzzy not
Deterministic case or the Imprecise information of parameter, the method mainly using monolayer membership function is to fuzzy uncertainty event
Or parameter is simulated, to be described with being subordinate to angle value.In real application systems, uncertain event becomes to become increasingly complex,
Uncertain parameter substantial amounts and relation is complicated, substantially increase event or parameter itself and information each other
Fog-level, seems clearly disadvantageous based on the monolayer membership function method of Zadeh fuzzy set and TYPE1 fuzzy set,
Analyze and process these fuzzy uncertainty events or parameter with being difficult in direct analog information.It can be seen that, new forms of energy user divide
Cloth photovoltaic generating system day output calculate prior art all not comprehensively consider influence factor uncertainty and with
Machine, the computational methods suitability, practicality and application are also difficult to be met.
