Simulation results on the studied microgrid with the high penetration of wind and photovoltaic generator demonstrate that the proposed DMPC is able to regulate frequency deviation and control indoor temperature deviation as a user preference. This paper proposes a multi-objective decentralized model predictive control (DMPC) for controlling the power consumption of IACs to reduce MG frequency fluctuation and control the variation in indoor temperature. The variation in indoor temperature should be controlled to fulfill residential comfort. Nevertheless, these IACs, regulating power, can cause the deviation of indoor temperature from the temperature setting. The power consumption of IACs can be regulated to suppress frequency fluctuation.

Smart loads such as inverter air conditioners (IACs) tend to be used for ancillary services in power systems. Consequently, the system exhibits steeper frequency nadir and the rate of change of frequency (RoCoF), which may degrade the dynamic performance and cause the severe frequency fluctuation of the system. However, the inverter interfaced RESs reduce the total inertia and damping properties of the traditional MG. The intermittent RES, such as wind turbines and photovoltaic generators, can be connected to the MG via a power electronics inverter. Microgrid (MG) is a novel concept for a future distribution power system that enables renewable energy sources (RES). Dynamic simulations in a six-machine two-area system and an isolated microgrid with wind power verify the effectiveness of the proposed control strategy. The proposed control strategy achieves an improved frequency regulation effect with fewer communication demands. Additionally, a recovery method for FFAC units is proposed to mitigate the power rebound after regulation. Based on this, the transforming time interval method is presented to determine the ON/OFF status of FFAC units to provide the required regulation power.

In SFR, a constant equivalent duty ratio method is raised to keep the regulation power stable over a long instruction interval. Furthermore, a recovery method is presented to stably restore the IAC units to their initial operating states after regulation. A random number generation method is proposed to stochastically trigger IAC units based on the frequency deviation in real time. In PFR, the regulation power is provided by adjusting the setpoints of the IAC units. This paper presents a coordinated control strategy for frequency regulation in which inverter air-conditioning (IAC) units are used to perform primary frequency regulation (PFR) and fixed frequency air-conditioning (FFAC) units are used to perform secondary frequency regulation (SFR). is a member of Building Trades Association and the ACT program.The increasing penetration of renewable generation presents challenges for system frequency regulation due to short-term power fluctuations and system inertia reductions.
