N2 - This paper studies a harmonized energy management strategy for houses with highly penetrated photovoltaic (PV) based on low temporal-spatial resolution state of charge (SOC) scheduling and high temporal-spatial resolution power balancing control. Energy market in residential sector is rapidly growing due to highly penetrated PV. It requires safety, reliability, economic efficiency, environment-friendly and fair control. Our target is to develop the energy management system (EMS) satisfying previous requirements. In this paper, load aggregator's targets are to decrease peak-to-peak interconnection point power flow and achieving harmonized battery energy storage system (BESS) control. Load aggregator makes SOC schedule and interconnection point power flow bandwidth based on hourly forecasting data in a day ahead. On the day, BESSs are minutely controlled to decrease excess power flow compare to the scheduled power flow bandwidth based on SOC schedule. Simulation results show reduction of the peak-to-peak interconnection point power flow and power fluctuation due to smoothing effect and discuss about fairness of the BESS control.
