Detailed Description
The technical solution of the present disclosure is further described in detail by the accompanying drawings and examples.
A flowchart of one embodiment of an energy scheduling method of the present disclosure is shown in fig. 1.
In step 101, the energy control device determines the remaining energy amount and the expected energy consumption of the current area. In some embodiments, the energy control device may be connected to the energy storage device and the energy consumption device in the area, obtain the remaining energy of the energy storage device, and predict the expected energy consumption in the next period of time or the remaining period of time of one power distribution cycle according to the current energy consumption condition of the energy consumption device, the next production plan, and other information.
In step 102, energy scheduling information is generated based on the remaining energy amount and the expected energy consumption. In some embodiments, the energy scheduling information may be an energy input request to apply for energy from energy storage devices in other areas if the remaining energy amount is less than the expected energy consumption; in other embodiments, the energy scheduling information may be an energy output request to provide energy to energy storage devices in other areas if the amount of remaining energy is greater than the expected energy consumption.
In step 103, the blockchain information including the energy scheduling information is issued on the blockchain network where the energy control device is located, so that each energy control device on the blockchain network performs energy scheduling according to the blockchain information and the energy usage of the corresponding area. In some embodiments, each energy control device located on the blockchain network can receive blockchain information from other nodes, parse and store the blockchain information.
By the method, whether the expected energy consumption of the region is matched with the residual energy quantity can be determined in time and reported to the block chain network, and each energy control device on the block chain network can execute energy scheduling analysis by using the block chain information, so that decentralized scheduling of energy among the regions is facilitated, the problem of energy shortage of part of regions is solved, energy waste of other regions can be avoided, and the utilization rate of energy is improved.
Another embodiment of the energy scheduling method of the present disclosure is shown in fig. 2, wherein the left and right dotted lines are respectively executed by different energy control devices in the blockchain network. The energy control device performing the left step requires energy input and the energy control device performing the right step is able to provide redundant energy.
In step 201, the energy control device determines the remaining energy amount and the expected energy consumption of the current area.
In step 202, the energy control device determines whether the remaining energy amount is less than the expected energy consumption. In case it is determined that the remaining amount of energy is less than the expected energy consumption, step 203 is performed. In some embodiments, if it is determined that the remaining energy amount is equal to the expected energy consumption, no operation is performed. In some embodiments, if it is determined that the remaining energy amount is greater than the expected energy consumption, the energy control device may actively generate an energy output request and generate blockchain information to be issued to the network, so that the energy control device requiring energy input determines a node capable of providing energy according to the received energy output request; the energy control device may not perform the operation until the blockchain information including the energy input request is received.
In step 203, the energy control device generates an energy input request based on the remaining energy amount and the expected energy consumption.
In step 204, the energy input request publishes blockchain information including the energy input request on the blockchain network.
In step 205, each energy control device on the blockchain network receives, stores, and parses blockchain information. When the energy control device with the remaining energy amount larger than the expected energy consumption receives the blockchain information and determines that the blockchain information includes the energy input request, step 206 is executed.
In step 206, an energy output request is generated based on the remaining energy amount and the expected energy consumption, wherein the energy output request includes energy balance information. In some embodiments, the energy balance information is the remaining energy amount-the expected energy consumption. In some embodiments, to avoid repeated scheduling of energy, the energy storage device may reserve part of the energy for standby, and the energy margin information is the remaining energy amount-expected energy consumption-reserved energy amount. The reserved energy quantity can be a preset value and can also be determined according to the current energy consumption and the production work arrangement.
In step 207, the blockchain information including the energy output request is issued on the blockchain network where the energy control device is located.
In step 208, the energy control device with the remaining energy amount less than the expected energy consumption determines whether the blockchain information is received and determines whether the energy output request is included in the blockchain information. If it is determined that the blockchain information including the energy output request is received, step 209 is performed.
In step 209, an energy scheduling target node and an energy scheduling amount are determined according to the expected energy consumption, the remaining energy amount, and the energy headroom information in the energy output request. In some embodiments, the total energy regulation amount is the expected energy consumption — the remaining energy amount. In some embodiments, in consideration of the problem of energy loss during transmission, the total energy regulation amount may be (expected energy consumption-remaining energy amount) × (102-103)%, so as to avoid energy waste and prevent insufficient energy regulation due to transmission loss.
In some embodiments, in a case that a sum of the energy margin information and the remaining energy amount in a single energy output request is not less than the expected energy consumption, it may be determined that the energy scheduling target node is a source node of the energy output request, and the energy scheduling target node is applied for the scheduled energy scheduling amount, which is a total energy scheduling amount.
In some embodiments, in a case where the sum of the energy margin information and the remaining energy amount in a single energy output request is less than the expected energy consumption, but the sum of the energy margin information and the remaining energy amount in a plurality of energy output requests is greater than the expected energy consumption, a plurality of energy scheduling target nodes and an energy scheduling amount for each energy scheduling target node may be determined according to the plurality of energy output requests, an energy scheduling amount for each energy scheduling target node is determined, and the energy scheduling amount for each energy scheduling target node is summed to be a total energy scheduling amount.
In some embodiments, to avoid the situation that the energy demand cannot be met by inter-region energy scheduling, the scheduling energy may be applied to the common energy storage node when the sum of the energy margin information and the sum of the remaining energy amount in the energy output request is less than the expected energy consumption, or when the blockchain information including the energy output request cannot be received after a predetermined time period after the blockchain information including the energy input request is issued. In some embodiments, the common energy storage node may have a device connected to the blockchain network, and may generate blockchain information by using the common energy storage node as an energy scheduling target node; in another embodiment, the common energy storage node may be independent of the blockchain network, and the energy control device sends the energy application request to the common energy storage node according to the address orientation of the common energy storage node.
In some embodiments, the energy prices may be different for each region, and energy unit price information may be included in the energy output request. When determining the energy scheduling target node and the energy scheduling amount, the energy control device may consider energy unit price information of each area, and select a scheme with the least cost from the feasible schemes to perform energy scheduling.
In some embodiments, the scheduling may be performed according to the distance between the regions, considering the scheduling efficiency and the transmission loss, without considering the energy price, or the energy price is the same.
In step 210, the energy control device generates an energy application request and issues blockchain information including the energy application request on a blockchain network in which the energy control device is located. In some embodiments, the energy control device may also control the energy storage device to which it is connected to prepare to receive an energy schedule over the energy network.
In step 211, each energy control device on the blockchain network receives blockchain information. If the energy control device that is expected to consume less energy than the remaining amount of energy determines that blockchain information including the energy application request is received, step 212 is performed.
In step 212, the energy control device determines whether it matches the energy scheduling target node in the energy application request. If so, go to step 213; and if not, storing the block chain information and not performing other operations.
In step 213, an energy output instruction is sent to the energy storage device in the current area, so that the energy storage device schedules energy meeting the energy scheduling amount to the energy storage device in the source node area of the energy application request through the energy network.
By the method, the equipment lacking energy can initiatively initiate a request through the blockchain information, each region can further issue the capability of providing energy through a blockchain network, energy scheduling and transaction information are recorded by each node in the network through the interaction of the blockchain information and the energy application condition, so that the transaction is completed, repeated transactions are avoided, the safety record of the transaction record is guaranteed, the transaction record is not tampered, and inter-region settlement is facilitated.
A flowchart of yet another embodiment of the energy scheduling method of the present disclosure is shown in fig. 3.
In step 301, energy is applied to the common energy storage device at the beginning of a deployment cycle.

A block chain network exists in a factory, and each area is respectively provided with energy control equipment which is used as a block chain link point to access the block chain network. In some embodiments, the common stored energy may reserve a portion of the energy for standby.
In step 302, the energy control device determines the remaining energy amount and the expected energy consumption of the current area.
In step 303, the energy control device generates energy scheduling information based on the remaining energy amount and the expected energy consumption.
In step 304, the blockchain information including the energy scheduling information is distributed on the blockchain network where the energy control device is located, and the blockchain information is received and stored.
In step 305, the energy control device performs energy scheduling according to the blockchain information and the energy usage of the corresponding area. In some embodiments, energy control devices may negotiate energy schedules between themselves in the manner described in the embodiment of fig. 2.
In step 306, the total energy consumption of the current region in the energy deployment cycle is counted according to the blockchain information. In some embodiments, the fluctuation of energy consumption within or during a cycle may also be counted.
In step 307, the energy usage of the current region is assessed. For example, for areas with large energy consumption fluctuation, suddenly increased energy consumption, or unmatched energy consumption and production capacity, whether abnormal loss exists or not is checked, and therefore each area is urged to save energy in the area.
In step 308, the amount of energy requested is adjusted. In some embodiments, the trend of the energy usage may be adjusted for the energy amount of the energy source applied to the common energy storage device at the beginning of each deployment cycle. In another embodiment, the amount of energy applied may also be adjusted in conjunction with the subsequent production schedule.
