考虑源-荷不确定性的微能源网区间规划方法OA北大核心

The optimal configuration of source-storage in micro energy grid(MEG)is a primary challenge at the early stage of its construction since there exist complicated energy flows.In addition,the uncertainties(especially the stochas-tic fluctuations of wind,solar,and multi-energy load power)in MEG are difficult to describe and overcome.To address these problems,the uncertainties of renewable energy and load demand are described as intervals,the minimization of annual converted investment cost is taken as the objective,and a linear AC power flow model is coupled.The constraints of cool/heat/electric power balance,node voltage static security,line capacity and heat pipe transmission power are taken into account,and the indeterministic constraints are transformed into deterministic ones based on the interval linear pro-gramming theory,thereby constructing an interval-based optimal planning model of MEG with the consideration of source-load uncertainties.The feasibility and superiority of this model are verified by case studies and analyses,indicat-ing that the planning scheme can adapt to different uncertain scenarios and ensure the system's stable operation.
