Embodiment Construction

[0024] Such as figure 1 As shown, it is a blockchain-based energy system optimization method involved in this embodiment, including the following steps:

[0025] Step 1. Record the inherent scene information of the power system in the genesis block;

[0026] Step 2. Each node of the blockchain network, that is, the miner broadcasts its objective function and constraints to the entire network;

[0027] Step 3. The node collects and packs all legal broadcasts during this period in the block;

[0028] Step 4. The node solves the optimization model for this period, and packs the results into blocks;

[0029] Step 5. The node adds its packaged block to the local blockchain and broadcasts it to the entire network;

[0030] Step 6. After the other nodes receive the block, they verify the KKT condition of the received block. If the verification is wrong, discard the block; if the verification is correct, go to step 7;

[0031] Step 7. The node adds the block to the local blockcha...

Abstract

The invention provides a block chain-based energy system optimization method in complex scenarios after initialization. The optimization problem is solved through the nodes of the whole network, the node with the fastest solution obtains the block bookkeeping right and broadcasts it to the whole network, blocks received by other nodes are verified for correctness, the verified block is the globaloptimal solution of the convex optimization model of the power system, and can be confirmed and broadcasted to the whole network. The energy block chain model proposed by the invention can meet the requirements of the security, openness, throughput and the like of the complex optimization scene of the power system, and has the landing and application capability.

Description

technical field [0001] The present invention relates to a technology in the field of smart grid control, in particular to a blockchain-based energy system optimization method in complex scenarios. Background technique [0002] As a decentralized, trustless, open and transparent information technology, blockchain provides a brand-new solution to solve the trust problem between different subjects in the power system and improve the fairness and efficiency of the system. However, the existing research either does not deeply explore the specific implementation method of the application scheme on the blockchain; or develops based on the existing blockchain platform without considering its disadvantages in operating efficiency and scalability; or only considers Scenarios with simple models in power systems. In addition, in addition to value flow, the power system also involves a large number of physical constraints, and its complexity is much higher than most traditional industri...
