Coordinated Optimal Dispatch for Multiple Building Microgrids under Uncertainties - a Chance-constrained Stackelberg Game Approach

To deal with the uncertainties of distributed generation in the coordinated dispatch of multiple building microgrids, a chance-constrained Stackelberg game approach is proposed in this paper. Firstly, the building microgrid is modeled and the uncertainties of renewable energy are described by the probability density function based on the historical data. Then, a chance-constrained approach is adopted to make sure that the constraint conditions with random variables are valid at a certain confidence level. Finally, the simulation results demonstrate that the coordinated dispatch of multiple building microgrids under appropriate confidence levels can contribute to more consumption of renewable energy, which is cost-effective and reliable.
