Summary: Store can be to solve large-scale but second birth the sources of energy and the important step of net problem, however, store can investment cost of the system loss of dimension of tall, carry is big, and different type store can difference of existence of technical economy parameter. Accordingly, study different type store can of the system mix the port with optimize configuration and its economy to have very principal. Raise the capacity inside scene power station model with power model store can the system mixes configuration to optimize a method, with store can net income of systematic complete lifecycle most greatly target, use genetic algorithm to undertake begging solving; With Home Zhang power station of buccal area scene carries travel data is mixed actually current 3 kinds of mainstreams store can actual parameter is batteries exemple, analyse different sensitivity element to be opposite store can systematic type selecting and the influence that the capacity configures. Calculate exemple result to make clear: Capacity store can systematic economy is more sensitive to batteries price change; The economy that current batteries and super capacitance mix configuration is optimal.
Conclusion: (1) below current condition, electrochemistry capacity store can batteries economy is more sensitive to batteries price change, come when price fall after certain level, best capacity and power reach the sensitivity of the element such as allowance to be reduced considerably to batteries price.
(2) when electrovalency policy is not changed, lithium ion batteries and current batteries store can when the system is controlled to 1000 yuan in batteries price fall, complete lifecycle just has profit likelihood; And below the circumstance with batteries changeless price, time-sharing electrovalency fold needs to amount to 2 times the left and right sides, store can allowance is in 1 yuan / (KW · H) the left and right sides, complete lifecycle just has profit likelihood.
The article is opposite only store can the economy of systematic itself undertook an analysis, and to power station of new energy resources + store can of the system generate electricity integratedly cost still remains follow-up research. In addition, in the article store can the system discards as useless directly after reaching design life, did not consider ladder second use, the meeting is right store can of the system optimize configuration and economy to cause certain effect, need further research.
