    Analysis of the Impact of Microgrid Penetration on Power System Dynamics
    The paper proposes a stochastic model to analyse the dynamic coupling of the transmission system, the electricity market, and microgrids. The focus is on the impact of microgrids on the transient response of the system and, in particular, on frequency variations. Extensive Monte Carlo simulations are performed on the IEEE 39-bus system, and show that the dynamic response of the transmission system is affected in a nontrivial way by both the number and the size of the microgrids.

    Decentralized stochastic control of microgrids to improve system frequency stability
    The paper proposes a decentralized stochastic control of microgrids aimed at addressing both system frequency stability and microgrids' revenue. With the proposed control strategy, each microgrid decides, based on a set of stochastic rules, a measure of the frequency and microgrid operating conditions, whether if it should adopt a cooperative strategy where primary frequency regulation services are provided to the grid or a non-cooperative strategy, where it aims at maximizing its revenues. Simulations, based on the Monte Carlo approach, are performed on the IEEE 39 Bus System in order to validate the robustness of the proposed control strategy.

    On the Impact of Microgrid Energy Management Systems on Power System Dynamics
    This paper compares the impact of microgrids on the transient response of the transmission system, and, more specifically, on its frequency variations, when different control strategies and different storage capacities are employed. Extensive Monte Carlo simulations are performed based on the IEEE 39-bus system, and show that the dynamic behavior of the transmission system is affected in a non-trivial way by the control strategy of the microgrids energy management system and their storage capacity.
