Problems solved by technology

It can be seen that the current application of blockchain to participate in micro-grid transactions is still at the level of fusion concept; as an analysis level, there is no specific solution for using blockchain to participate in interconnected micro-grid systems

Embodiment

[0102] 3.1 Basic data

[0103] Construct an IMS containing three island microgrids, MG1 includes a conventional generator DG1 and a heating unit HEAT1, MG2 contains a conventional generator DG2 and a combined heat and power system CHP2, and MG3 includes a combined heat and power system CHP1. IMS topology such as Figure 4 shown.

[0104] A short-term forecast is made on the output power and load of wind and wind, and 20 minutes is selected as a dispatch cycle, and the heat demand and wind and wind output power prediction results within the consensus time are specified as follows: the heat demand of MG1 is 0.1MWh, and the wind and wind output power is 0.1MWh respectively , 0.2MWh, the thermal demand of MG2 is 0.08MWh, the optical output power is 0.1MWh respectively, the thermal demand of MG3 is 0.05MWh, and the wind and solar output power are 0.1MWh and 0.3MWh respectively. We predict the results of the initial load within one consensus time (i.e., three scheduling periods). ...

Abstract

The invention discloses a distributed optimization dispatching method of an interconnected micro-network based on an intelligent contract, which comprises the following steps: establishing a block chain of electric power transaction; setting the dispatching cycle, recording the electricity quantity sent and received in the dispatching cycle; the optimal dispatching model of interconnected micro-grid system being established and solved, and the optimal dispatching scheme being obtained. According to the optimal dispatching scheme, the transaction contents of the micro-grid involved in the transaction are determined, and the smart contract is signed and sent to other micro-grids in the network. The microgrid to reach consensus; verify the transaction, judge whether the transaction is safe ornot, cancel the transaction if it is not safe, complete the transaction if it is safe, and transfer funds between microgrids. The invention provides a distributed optimal dispatching model and a distributed iterative algorithm of an interconnected micro-grid system, and applies a block chain to the recording and value transfer of the distributed transaction, and signs an intelligent contract between the micro-grids, thereby solving the trust problem between the transaction parties and achieving high automation degree.

Description

technical field [0001] The invention relates to an intelligent contract-based distributed optimization scheduling method for an interconnected micro-network. Background technique [0002] Microgrid (MG) is an independently controllable system including loads and various distributed power sources. Generally, microgrids can be converted in grid-connected and islanded modes. With the development of microgrid, a new concept of interconnected microgrid system (IMS) is proposed, which shares load and reserve capacity with adjacent microgrids. By developing an interconnected microgrid system (IMS), it can be more flexible to ensure the full use of renewable energy, reduce operating costs, and improve power supply reliability. From the perspective of interactive energy, microgrid can be regarded as having attributes of both sellers and buyers. During different time periods, the microgrid acts as a seller or a buyer depending on real-time operating conditions and net power distrib...
