This paper describes a model for power distribution grid simulation with distributed generation, designed to be a simulation environment of two proposed elements: (I) an algorithm to reconfigure the circuit topology to enable a microgrid during an outage of power supply, and (2) a specific limiter to allow safe operation of distributed generation in the network. Moreover, an interface of the simulation model with a SCADA was designed to suggest possible operational screens for both: the generator and the utility. The simulation model was designed with a synchronous generator with all cogeneration typical controls: speed, active power, voltage, reactive power and power factor. Thus, it is possible to simulate critical situations with all control modes available in a typical cogeneration plant in addition to the proposed limiter. Due to the immense number of possible combinations of circuit breakers in the grid, the proposed algorithm is based on genetic algorithms to enable a fast enough autonomous reconfiguration to avoid the outage perception by the customer.
