Planning Method for No-Carbon Building Comprehensive Energy Carrier Considering The County-Level Rooftop Photovoltaics

The county-level rooftop photovoltaics can promote the realization of no-carbon building comprehensive energy carrier. But the impacts of county-level rooftop photovoltaics on the planning of no-carbon building comprehensive energy carrier is insufficient. In this context, this paper proposes a robust planning method for the no-carbon building comprehensive energy carrier considering the county-level rooftop photovoltaics. Firstly, the basis structure of the no-carbon building comprehensive energy carrier is described. Especially, the electricity from the county-level rooftop photovoltaic and external power grid can be used to supply the electric and thermal loads. In addition, the basic planning model of the no-carbon building comprehensive energy carrier is constructed for minimizing the total investment and operation costs. Then, a robust optimization planning method is proposed considering the four-season output uncertainties of the county-level rooftop photovoltaics. Especially, the uncertainty set of the forecast output of photovoltaics is constructed. Meanwhile, an easily tractable solution method for the robust planning model is proposed. Finally, the CPLEX, Yalmip and Matlab are utilized to prove the effectiveness of the proposed model.
