It is to be understood that the described embodiments are merely exemplary of the invention, and not restrictive of the full scope of the invention. Other embodiments, which can be derived by one of ordinary skill in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
The invention relates to a transaction mode evaluation method based on a multi-region interconnected power system, as shown in fig. 1, fig. 1 is a multi-region interconnected power system model in the invention.
The invention specifically comprises the following steps:
and 2, establishing a block chain technology-based bilateral transaction framework of the multi-region interconnected power system based on the bilateral transaction model of the multi-region interconnected power system.
and 4, introducing a peak-valley electricity price principle to realize the sectional proportion sharing of the grid loss electricity price.
The step 1, establishing a bilateral transaction model of the multi-region interconnected power system, comprising the following steps:
the network splitting suitable for bilateral transaction aims at establishing the relationship between each transaction and an actual physical network, namely, a proper branch is selected according to bilateral transaction to decompose and redraw the physical network into a radial network comprising all nodes, parallel flow generated by bilateral transaction is equivalent to a reserved branch network, and then an association model of all bilateral transactions and physical paths is established. For bilateral transaction between A and B, when the contract path is designated as a branch A-B, the original network load flow result obtained by calculation according to the transaction assignment method is in accordance with reality. A tree type network model reflecting the bilateral transaction contract amount and the contract path can be established by using a network splitting method, corresponding contract power is assigned to the tree branches of the converted bilateral transaction network, the relationship between the bilateral transaction network trend and the original network trend is established, and finally the corresponding relationship among the contract power, the contract path and the actual branch trend is established by using the network splitting method.
The step 2, based on the multi-region interconnected power system bilateral transaction model, establishing a block chain technology-based multi-region interconnected power system bilateral transaction framework, including:
the technical characteristics of peer-to-peer, safe, credible, public and transparent of the block chain can seamlessly meet market transaction requirements of the multi-region interconnected power system, and the block chain technology is introduced to reconstruct an electric energy transaction framework of the region interconnected power system.
(1) As shown in fig. 1, transaction subjects including a power source, a power grid enterprise, a power consumer, and the like in fig. 1 may be abstracted into individual transaction nodes, each node stores all transaction records, and all nodes maintain transaction data together. Thus, each transaction body is regarded as a peer node, and point-to-point transaction is realized.
(2) In the point-to-point transaction, both parties trade directly without any third party.
(3) All transactions are based on intelligent contracts, and the intelligent contracts comprise contents such as transaction electric quantity, settlement price, settlement time and the like and are coded by encryption algorithms.
(4) All transaction operations are automatically executed after meeting the conditions without any manual intervention.
(5) A prioritization strategy is added to prevent network congestion during broadcast of multiple transactions.
The bilateral transaction framework based on the block chain technology is constructed, and the core technology of the bilateral transaction framework is the compilation of an encryption algorithm and the generation of an intelligent contract. The encryption algorithm is the guarantee of the fairness and the confidentiality of the block chain technology, and the calculation of the transaction related data in the intelligent contract is the basic guarantee of the electric energy transaction.
The step 3, embedding a network loss sharing method under a bilateral transaction framework intelligent contract system of the multi-region interconnected power system, comprising the following steps:
grid losses are generated in the case where the grid is used in common for all power transactions and are an important component of the cost of transmitting power. Theoretically, the distribution should be made according to the principle of "who causes and who is responsible" and the use degree of the transmission line by each power load or transaction. In the total network loss of the system, the network loss part generated by the independent action of each transaction and the cross network loss generated by the interaction between the transactions exist. The network loss cost is distributed to market members and embedded into an intelligent contract system, which is an important step for further perfecting and innovating a bilateral transaction method of a multi-region interconnected power system.
The basic idea of apportionment of transactions is to follow the branch power proportion sharing principle, that is, apportionment is performed according to the proportion of each transaction flow in each branch power flow. Since the active loss on the branch is in direct proportion to the active power flowing through the branch, the power flow distribution caused by the transaction in each branch can be calculated, and then the power flow distribution is divided according to the proportion of the respective power flow in the capacity of the branch.
Therefore, the circulation path of bilateral transaction flows of the multi-region interconnected power system in the actual network is simulated, the essence is that the flow of the branch is assumed to be formed by mixing the flows of all transactions, and the proportion of the network loss to the total network loss is the same as the proportion of the flow of each transaction to the total flow.
The method for distributing the network loss is to apply the network splitting method in the step 1 to distribute the network loss, and the method for distributing the network loss specifically comprises the following steps:
step (1): obtaining a bilateral transaction network and a transaction transfer distribution factor matrix by adopting a network splitting method;
step (2): performing alternating current power flow calculation on the original network in a given bilateral transaction operation mode to obtain branch active power and active network loss in the original network a;
and (3): in order to obtain the network loss which should be shared by each group of transactions, the trend contribution of the group of transactions to each branch of the original network a is calculated. Accordingly, the sum of the network losses caused in the branches of the original network is calculated.
And (4): because the network splitting method is carried out on the premise of the assumption of direct current power flow, the conclusion that the active loss of the branch is in direct proportion to the active power flowing through the branch can be utilized on the basis, and finally the network loss to be shared by the transaction is obtained.
The network division method is applied to carry out network loss allocation to obtain specific algorithm description, the algorithm can effectively improve the integrity and the practicability of a block chain intelligent contract system, effectively improve the feature description content of each node in a block chain, and realize the establishment and the improvement of a bilateral transaction framework of a multi-region interconnected power system.
And 4, introducing a peak-valley electricity price principle to realize the sectional proportion sharing of the grid loss electricity price.
The block chain intelligent contract comprises a transaction time element, peak-valley electricity prices are introduced according to different transaction times, on the premise of reasonably distributing the grid loss, the grid loss electricity prices with economic reference significance are calculated, and an intelligent contract system under a multi-region interconnected power system bilateral transaction framework based on the block chain technology is further perfected.
