Description
Technical field：
The invention belongs to technical field of energy utilization, and in particular to a kind of Distribution of Natural formula energy system of coupled solar
System.
Background technology：
Distributed energy resource system is the energy supplying system for traditional centralized energy-provision way, distributed energy resource system
It is directly facing user, simultaneously supplying energy is produced in situ in by the demand of user, is that can meet the energy of multiple target with multiple functions
Measure conversion system.Compared with traditional centralized energy-provision way, distributed energy need not build big electricity close to user side
Net, big heat supply network, avoid the long-distance sand transport of the energy, can save construction investment, and reduce line loss and operating cost.Point
The cloth energy can be distributed formula photovoltaic, distributed wind energy, NG Distributed Energy System (also referred to as natural gas cold, heat and electricity three-way
For system) etc. diversified forms.NG Distributed Energy System by gas turbine, waste heat boiler, steam turbine, absorption heat pump and

Suitable output obtains middle low-temperature heat source, thus in, low-grade utility be that current solar energy low cost, scale application are most important
Field.Solar energy heating technology is in solar energy, one kind of low-grade utility technology, includes mainly vacuum tube heat collection function and tablet collection
Hot two ways, technology maturation and energy-saving effect is notable have been widely used in China resident's hot water supply field.But due to
Solar energy the characteristics of there are itself poor continuities, it is difficult to ensure reliable heat source output, if being used for district heating, hold over system will
It is very huge, and since the heat source grade exported is relatively low, it is difficult to obtain the efficient utilization of low cost.
