AI Technical Summary

Technical Problem

Existing research has failed to effectively consider the impact of distributed photovoltaic aggregators as price setters on market clearing prices, and has neglected their safety verification in the distribution network, resulting in an unreasonable and insecure electricity market trading structure.

Method used

A Stackelberg game model with one master and multiple slaves is established to maximize the revenue of distributed photovoltaic aggregators. The social welfare maximization of the market trading center and the safety verification of the power distribution system operator are incorporated into the lower-level model. The model is solved by a phased solution strategy and the data-driven two-layer reconstruction optimization algorithm DOMINO.

Benefits of technology

This has increased the revenue of distributed photovoltaic aggregators, ensured the safe and stable operation of the power distribution system, provided a scientific and reasonable basis for decision-making, and promoted the healthy and sustainable development of the electricity market.
