ECONOMIC DISPATCH OF POWER SYSTEMS WITH VIRTUAL POWER PLANT BASED INTERVAL OPTIMIZATION METHOD

Abstract

Load prediction and power prediction uncertainties are inevitable aspects of a virtual power plant (VPP). In power system economic dispatch (ED) modeling, the interval is used to describe prediction uncertainties. An ED model with interval uncertainty is established in this paper. The probability degree definition is adopted to convert the interval-based economic dispatch model into a deterministic model for the purposes of solving the modeling problem. Simulation tests are performed on a 10-machine system using professional optimization software (LINGO). The simulation results verify the validity of the proposed intervalbased scheme for the economic dispatch of a power system with VPP.
