Software Tool Application for Dynamic Response Analysis of a Microgrid

Microgrid (MG) robustness and flexibility are some of the issues to improve for complying with grid connection rules. To this purpose, an ex-ante short-term programming tool and optimizing procedure, that updates set-points in a time step of 15 minutes, should be developed to define the production of programmable power generation plants and forecast the production of non-programmable power plants. During the updating time steps, it should be considered that some dynamic events can suddenly modify operation with respect to established set-points. Dynamic tests need to be conducted for evaluating MG behavior, over a 15-minutes time horizon, in case of wind, solar radiation or load variations. In this paper, the MG dynamic response to unpredictable variations of source availability and load is evaluated in order to ensure the compliance with technical and economical requirements.
