Two step optimal dispatch based on multiple scenarios technique for active distribution system with the uncertainties of intermittent distributed generation and load considered

This paper presents a two step optimal dispatch model based on multiple scenarios technique for active distribution system (ADS) where the uncertainties of intermittent distributed generation and load are considered. The probabilistic models of wind power and different loads in ADS are discussed, firstly. Secondly, latin hypercube sampling and discrete latin hypercube sampling are introduced to construct scenarios. On the basis of these, a model included with day-ahead dispatch and real-time dispatch is proposed. The objectives consist of profit of power supply company, penetration of wind power and etc. The constraints are comprised of power balance, real-time dispatch power limitation and etc. The effectiveness and validity of proposed model is verified by cases.
