...The physical laws that approximate the MG slow dynamics under the study are similar to those that govern the active power control in a diesel group [ 33 ], being the parameterized model structure represented in Figure 6....

...Therefore, suitable dynamic equivalents for MG comprise the detailed model of the main storage device VSI control and the MG slow dynamics equivalent model corresponding to the aggregated model of the remain MG components, as it can be observed from Figure 4. Therefore, the aim of the system identification procedure is to identify the equivalent model of the MG slow dynamic behavior [ 33 ], [48]....

...The detailed model of the whole MG network is divided into two parts: The internal subsystem that has to be retained for detailed analysis and the external subsystem that will be replaced by the equivalent model [ 33 ], [48], as depicted in Figure 2. The dynamic system to be identified consists of a set of differential and algebraic equations corresponding to the dynamic models of the several microgeneration systems describing the state ......

...System identification techniques in combination with some general knowledge of network structure, if applied adequately, are suitable for DNC model development as they rely on actual measured system responses and can be easily validated [31]-[ 33 ], [38]-[40]....

...Therefore, appropriate dynamic equivalents for MG are required in order to speed up numerical simulations [ 33 ], [48] and to represent the MG’s dynamic behavior with respect to the MV network....

...As a result of the droop control implemented in the VSI, the main storage unit will support all power deviations by injecting or absorbing some amount of active power proportionally to the MG frequency deviation [6, 17]....

...More recently EPSO was successfully applied in training a FIS model under an entropy criterion for wind power prediction [214], denoting that EPSO performs well under different criteria, and its robustness has effectively been exploited as a nonlinear global parameter estimation tool to build dynamic equivalents for MG using MSE criterion [17]....

...86 with respect to the MV networks, it is necessary to speed up numerical simulations with limited technical resources and therefore the development of dynamic equivalents for MG is required [16, 17]....

...In this case the physical laws that approximate the MG slow dynamics under the study are similar to those that govern the active power control in a diesel group [17]....

...The mathematical models adopted to represent the dynamic behaviour of each MG generation system were adapted in order to be linked together with the algebraic equations describing the LV network forming thus the whole model of a MG as a multi-machine power system model [16, 17] in chapter 5....
