Embodiments include a controller in communication with the resources to control operation of the resources and operative to determine an optimal load balance based on load and renewable generation forecast information; transmit load and generation schedules to a generation controller that operates the resources in accordance with the schedules; calculate a frequency set point for energy storage resources in the microgrid based on the optimal load balance of the energy storage resources, droop settings, rated power, and the frequency of the energy storage resources; and to control the frequency set point of the energy storage resources to achieve the optimal load balance. Numerous additional aspects are disclosed.1/8 100 102 103 104 ~ -106 110 WEATHER DATA RENEWABLE FORMATION FEED GENERATION MON FORECAST MODULE 108 , 112 HISTORICAL I LOAD & GENERATION GENERATION CONTROL DATA 114 120 ISLANDING SWITCH 116 122 MACROGRID FIG. 1
