In one embodiment, the method specifically comprises the following steps:
1. energy sub-region classification
Setting a regional energy system to be divided into n energy subregions, wherein m renewable surplus energy subregions are arranged at the initial moment of a period Tx, and surplus power of the regional energy system is as follows:
Psurplus＝{(Pes1，Phs1)，(Pes2，Phs2)，(Pes3，Phs3)，…，(Pesm，Phsm)}
wherein Pes is surplus electric energy, and Phs is surplus heat energy.
k sub-areas of renewable shortage of energy, associated with the load, the power of the shortage being:
Pshortage＝{(Pel1，Phl1)，(Pel2，Phl2)，(Pel3，Phl3)，…，(Pelk，Phlk)}
wherein Pel is the demand of electric energy, Phl is the demand of heat energy.
If the renewable energy is transported, the surplus subarea energy is consumed so as to reduce the expenditure of energy purchased by the energy shortage subarea to the power grid and the natural gas pipeline network, and S schemes are shared.
It is clear that some of these solutions are not reasonable, for example, when Pesi is 0, it still participates in the energy transmission scheme of Pelj, which can be eliminated by preprocessing, thereby reducing the subsequent computational pressure.
The pretreatment method comprises the following steps:
dividing surplus subregions into three categories according to the types of surplus energy sources:
Pes-only＝{Pesi|i∈(1,2,3,…,m),and Phsi＝0}
Phs-only＝{Phsj|j∈(1,2,3,…,m),and Pesj＝0}
Pes-hs＝{(Pesq,Phsq)|q∈(1,2,3,…,m),and(Pesq≠0,Phsq≠0)}
and secondly, similarly, dividing the shortage subareas into three types according to the types of the shortage energy sources:
Pel-only＝{Peli|i∈(1,2,3,…,k),and Phsi＝0}
Phl-only＝{Phlj|j∈(1,2,3,…,k),and Pesj＝0}
Pel-hl＝{(Pesq,Phsq)|q∈(1,2,3,…,k),and(Pelq≠0,Phlq≠0)}
2. aiming at the above classification, according to the principle of a divide-and-conquer algorithm, the following 5 combinations are constructed:
Pes-only——Pel-only
Phs-only——Phl-only
Pes-hs——Pel-only
Pes-hs——Phl-only
Pes-hs——Pel-hl
3. the number of two set elements in each combination was calculated to form the following energy delivery scheme (i.e., initial energy complementation strategy):
S′＝{S′1，S′2，S′3，S′4，S′5}。
fig. 4 is a schematic flowchart of the refinement step of S103 in the embodiment of the present invention, and as shown in fig. 4, S103 includes:
step S401: searching an initial energy source complementation strategy corresponding to each surplus energy source subregion from the plurality of initial energy source complementation strategies;
step S402: extracting a distance matrix corresponding to the initial energy complementation strategy from an energy transmission distance matrix corresponding to the type of the combined energy to which the initial energy combined data corresponding to the initial energy complementation strategy belongs;
step S403: calculating energy transmission benefits corresponding to each surplus subarea according to the distance matrix corresponding to the initial energy complementation strategy and the preset energy transmission benefit model;
step S404: under the condition that the energy transmission benefit is larger than zero, summarizing the initial energy complementation strategies corresponding to the energy transmission benefit to obtain an initial energy complementation strategy set corresponding to each surplus subarea;
step S405: and performing descending order arrangement on the initial energy source complementation strategies in the initial energy source complementation strategy set according to energy source transmission benefits, and selecting the initial energy source complementation strategy corresponding to the maximum energy source transmission benefit as the target energy source complementation strategy corresponding to each surplus energy source subregion.
In an embodiment, each initial energy source combination data in the plurality of initial energy source combination data corresponds to each initial energy source complementation strategy in the plurality of initial energy source complementation strategies in a one-to-one manner; and calculating which shortage energy sources are transmitted to the surplus energy source sub-region according to the principle that the surplus energy source sub-region is preferred. The method comprises the following specific steps:
it is determined which of the 5 types in the previous embodiment the surplus energy sub-regions can be categorized into.
Secondly, calculating an energy transmission distance matrix of the scheme to which the type belongs
X surplus energy sub-regions and y shortage energy sub-regions are arranged:
there is line loss in the energy delivery process, whether in the form of electricity or heat. If the electric energy is transmitted, the average loss of each kilometer of the line is recorded as Pekm; if thermal energy is transported, the average loss per kilometer of the line is Phkm. Once the cloud platform establishes an energy delivery relationship between renewable energy sources in the regional energy system, the average construction cost to period Tx of the renewable energy sources under the strategy is calculated as follows:
CTinvest＝{CTinvest1，CTinvest2，CTinvest3，…，CTinvests}
assuming that the prices of electricity sold and purchased in the whole regional energy system are uniform, mi surplus energy sub-areas and ki sub-areas needing energy purchase exist in the ith scheme, and the distance matrix of the scheme extracted from the transmission distance matrix is as follows:
assuming that only energy exchange between energy sub-areas is performed, and the power grid and the heat distribution pipeline network only act as a bridge, the benefit relation (i.e. the preset energy delivery benefit model) can be expressed as:
where ρ isesellSelling prices, rho, for electric energy in surplus sub-areashsellSelling price for heat energy, pebuyPurchase price of electric energy, rho, for sub-area of energy shortagehbuyPurchase price for heat energy, pnetworkFor selling electricity prices, rho, to the gridheatIs the official heat energy price. T isi≤TxIs the transaction time for the ith scenario. When (bf)i>At 0, the ith scheme enters the decision pool. The finally constructed decision pool for all energy sources is as follows:
BF＝{(bf)1，(bf)2，(bf)3，…，(bf)i，…，(bf)w}
and the decision pool comprises a target energy complementation strategy corresponding to each surplus energy subregion.
Further, r target energy complementation strategies exist in the decision pool for the same surplus energy sub-region, and one target energy complementation strategy needs to be selected from the r target energy complementation strategies and issued to the corresponding sub-region edge gateway. And if a decision needs to be issued to the v surplus energy sub-region, selecting all target energy complementation strategies associated with the decision pool from the decision pool, arranging the strategies in a descending order according to the (bf) value, issuing the first ordered target energy complementation strategy to the v surplus energy sub-region, and simultaneously opening an information channel of the shortage energy sub-region associated with the target energy complementation strategy to realize energy complementation between the surplus energy sub-region and the shortage energy sub-region.
Fig. 5 is a schematic flowchart of the refinement step of S104 in the embodiment of the present invention, and as shown in fig. 5, S104 includes:
step S501: generating a target instruction according to the target energy complementation strategy corresponding to each surplus energy subregion, and sending the target instruction to a subregion edge network corresponding to each surplus energy subregion;
step S502: and the sub-area edge network establishes communication between each energy sub-area and the shortage energy sub-area corresponding to each energy sub-area according to the target instruction so as to realize energy complementation between each energy sub-area and the shortage energy sub-area corresponding to each energy sub-area.
In an embodiment, after receiving the target energy complementation strategy issued by the cloud platform, the sub-region edge computing gateway establishes a communication link with the sub-region in short energy, and notifies the sub-region in short energy to send related information such as the microgrid address, the attribute of short energy, the power factor and the like of the received energy. After calculation, the sub-region edge calculation gateways form a local energy source transmission command matrix and send the local energy source transmission command matrix to the micro-grid in the administered region, so that energy source flow transmission is established by means of a public network. Meanwhile, the edge computing gateway starts timing, records and stores relevant parameters of local micro-grids and loads in real time, preprocesses the parameters and arranges key data. And after a period appointed with the cloud platform is timed, the sub-region edge computing gateway uploads the key data to the cloud platform so as to prepare the cloud platform for the next round of decision making.
