In the past few years, the presence of distributed generation (DG) in the power distribution systems have greatly evolved. An effective way of taking advantage of the DGs benefits is to aggregate them and its loads in a subsystem called mi-crogrid. This paper presents a primary and secondary distributed control approach applied to a microgrid that encompasses a three-phase photovoltaic generation unit of 5 kW, a full converter wind turbine system of 15 kW and a gas micro-turbine with 10 kW. The well-established droop control technique was applied for the microgrid primary control. The restoration of the frequency and voltage deviation from the nominal value was performed by a secondary control strategy. The multiagent based secondary control was developed using an open source platform named PADE (Python Agent Development Environment). The microgrid simulations were performed using PSCAD® software that provides a management and control library, written in Python 3 pro-gramming language, enabling the integration with the PADE platform. The performance of the droop control was observed through the appropriate power sharing of the microgrid sources. The communication between PSCAD and PADE was carried out, enabling the reading of simulation data and the sending of commands, in real time.
