Abstract
This paper presents a new centralized microgrid energy management system (EMS) formulation based on successive linearization. The presented formulation incorporates the control of energy storage systems (ESSs), controllable loads (CLs), and distributed generators (DGs). Two objective functions are formulated, (a) minimization of operational cost of DGs and cost of electricity bought from the grid, and (b) minimization of generation ramping. In order to mitigate the computational burden of centralized EMS schemes, we propose a solution methodology based on successive linearization of the microgrid non-linear optimization model. Several case studies are performed to optimize the operation of a test microgrid during a time span of 6 hours with a resolution of 15 minutes. Simulation results indicate the capability of the proposed EMS in reducing operational cost and generation ramping within acceptable computational times.
