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.
