Abstract-This paper proposes a distributed optimization model for community microgrids considering the building thermal dynamics and customer comfort preference. The microgrid central controller (MCC) minimizes the total cost of operating the community microgrid, including fuel cost, purchasing cost, battery degradation cost and voluntary load shedding cost based on the customers' consumption, while the building energy management systems (BEMS) minimize their electricity bills as well as the cost associated with customer discomfort due to room temperature deviation from the set point. The BEMSs and the MCC exchange information on energy consumption and prices. When the optimization converges, the distributed generation scheduling, energy storage charging/discharging and customers' consumption as well as the energy prices are determined. In particular, we integrate the detailed thermal dynamic characteristics of buildings into the proposed model. The heating, ventilation and air-conditioning (HVAC) systems can be scheduled intelligently to reduce the electricity cost while maintaining the indoor temperature in the comfort range set by customers. Numerical simulation results show the effectiveness of proposed model.

This paper reviews the various operation techniques of wind turbines within the stand-alone microgrid. First, the paper focuses on the feature and operation of the stand-alone microgrid when it includes wind turbines. Then, various methods to operate and control wind turbines within the stand-alone microgrid are introduced. In addition, main considerations are explained for the operation of a wind turbine generator (WTG) in a stand-alone microgrid. Finally, the technical challenges for this issue are discussed.Index Terms-Inverter based system, microgrid operation, stand-alone microgrid, wind turbine control

“…In practice, a significant part of the renewable energy might need to be either curtailed or dissipated in dump loads to prevent operation of the genset under low load conditions [2]. To address these problems, a Battery Energy Storage System (BESS), can be incorporated into the system creating a diesel-batteryhybrid mini-grid [3][4][5].…”
