Multi-objective optimal dispatch model of microgrid considering the uncertainty output of renewable energy sources

This paper presents a multi-objective optimal dispatch model based on chance constraint programming (CCP) for microgrid where the uncertainties of renewable energy sources (RES) and load are considered. The probabilistic model of PV, wind power and load are discussed, firstly. Secondly, sequence operation theory is introduced and applied to deal with the uncertainties. On the basis of these, a multi-objective dispatch model considering different operational status is proposed. The objectives consist of operational cost, compensation cost, environmental cost and etc. The constraints are comprised of power balance, power limitation and etc. The effectiveness and validity of proposed model is verified by case study.
