The energy structure is out of balance in China.This is a problem that desperately needs to be solved.And it is well known that the energy supply efficiency in China is low.Simultaneously,these phenomena can cause other problems that the environmental are becoming worse and worse.Therefore,it is pressing us to build an amicable and high-performance system.We as strivers in the energy industry should be fighting for that and make our own contribution.This article proposes a distributed multiple energy storage system.Electricity,heat,cold and gas are all reflected in this system.Furthermore,we invent an optimization model of the distributed multiple energy storage system.Then we create an optimization model of the HESS.These efforts will contribute greatly to the problems we have mentioned above.Firstly,we expound the actual state of affairs and the forward potential of the IES.In this context,this article put forward a distributed multiple energy storage system.This scheme is in line with the requirements and is scientific and reasonable.Therewith,we found the formula expressing of the energy supply equipment such as internal combustion generator and so on.Simultaneously,we dissect the element of the energy storage equipment.Particularly,we emphatically found the formula expressing of the electric energy storage equipment(ultracapacitors,lithium-ion batteries and compressed air storage).Secondly,we construct a distributed multiple energy storage system according to the achievements already accomplished hereinbefore.Meanwhile we tersely expound the working mechanism of the system that we have built up here on the strength of the running theory of the facility in the whole.In order to go further,we found the parameter optimization model of the distributed multiple energy storage system.We set a threefold goal to achieve satisfactory results.To make it more scientific and reasonable,we institute three different angle constraints,and they respectively are the constraints of the unit output,the equipment operation,and the amount of balance,and we use YALMIP+CPLEX to solve it.After the above work is completed,we need to move on to the next step and that is the optimization of the storage unit configuration.In this session,we employ the quadratic moving average filter method to complete the power distribution work.Beyond that,It is also quite necessary for us to ensure the continuity and the safety of all parts by energy balance regulation and SOC parameter limitation.After all of the above is done,we shall harvest the fruits of the optimal results of the HESS.Finally,we go into further discussion and calculation of the HESS.We ran a random combination of three different devices.For the three different combinations,we explore each one’s operation characteristics and investment cost in detail.Through complete calculation and comparative analysis,we got an important conclusion that the system coupled by the three devices presents the best performance and takes the lowest cost.After the above research work is completed,we make a deep exploration of the influence of the filter width parameters.We have learnt that the filter width parameters will have an influence on the computation of the apparatus parameter and the input cost of the ESS and it is worthwhile for the overall performance.
