| Abstract: |
| With the continuous penetration of IoT(Internet of Things) devices and distributed resources in the distribution network, the energy management of regional distribution network is facing new challenges. Therefore, a cloud-fog layered hierarchical energy management architecture is proposed, and the intelligent algorithm is used to realize the energy management and optimal decision-making of distribution system with multiple stakeholders. In the fog layer calculation, the data generated by smart meters and various IoT devices are calculated and processed with the help of machine learning. In the cloud layer calculation, the data interaction between cloud and fog and the collection of external information are used to carry out the overall optimization calculation of decision-making objective of distribution network by using intelligent optimization algorithm, so as to achieve the purpose of intelligent decision-making. The utility and income models of three stakeholders of common users, microgrid and distribution system operator are established. In the fog layer, the regression prediction of users’ electricity consumption behavior and new energy output data is realized. According to the users’ response to electricity price, the optimization decision of total purchasing load and retail price is made for distribution network in the cloud layer with the goal of maximizing social welfare, to realize the optimal management of the whole distribution network. The proposed method is simulated by the example of IEEE 33-bus system and the results verify the effectiveness of the proposed method. |
