A power output control and compensation (PCC) circuit operates within a distributed energy resource (DER) system. The PCC circuit is located in a battery power conversion system (PCS) and includes an input terminal to connect with a power source and an output terminal to connect with an electrical panel or load. A current sensing device is coupled between the input and the output terminals to measure a power level of the power source. A relay is coupled between the current sensing device and the output terminal and a processor selectively connects power from the power source to the electrical panel or the load based on the measured power level or based on other power measurements within the DER system. PCS-control of multiple power sources decreases cycle times for controlling distributed energy resources.

A power control system is disposed in a predetermined area. The power control system includes a server, a smart gateway device, a power detection device, a smart meter, a first power control device, a power generation device, a second power control device, a plurality of electronic devices, and a power storage device. The power detection device detects a value of a supply current per second of the first power of the first power control device. The power detection device detects a value of a used current per second of the second power of the second power control device. The power detection device provides a current difference between the value of the supply current and the value of the used current to the first power control device and the smart gateway device. The first power control device adjusts the first power at least based on the current difference.

A microgrid comprises an electric vehicle battery storage system that supplies a first DC signal, a bus bar that receives the first DC signal and provides a combined DC signal, a frequency variable and/or voltage variable inverter that receives the combined DC signal, converts, responsive to one or more control signals, the combined DC signal into a first AC signal having variable frequency and/or variable voltage, and provides the first AC signal having the variable frequency and/or voltage to the electrical loads of the facility, and a DC to AC that receives, responsive to the one or more control signals, the combined DC signal from the bus bar, and converts the combined DC signal to a second AC signal.

Energy flows are segmented into components for tracking the location of energy consumption and production. Data collected on energy flows is used to create profiles of energy production and consumption over specified time windows for specific clients. Data profiles are also created for an aggregation of clients. The portion of an energy flow that is distributed to each client within an area is calculated. Based on data obtained and portions calculated of the energy flow, incentives are created to encourage energy production and usage in locations that reduce energy losses due to transmission of the energy flow. Aggregated data and feedback information about production and consumption is sent back to clients. Incentives can be in the form of pricing adjustments for both production and consumption during specified time periods.
