This study proposes a real-time distributed energy resource (DER) coordination model that can exploit flexibility from the DERs to solve voltage and overloading issues using both active and reactive power. The model considers time-coupling devices including electric vehicles and heat pumps by deviating as little as possible from their original schedules while prioritizing DERs with the most urgent demand using dynamic cost terms. The model does not require a multi-period setting or a multi-period-ahead forecast, which enables the model to alleviate the computational difficulty and enhance its applicability for distribution system operators to manage the grids in real time. A case study using a Dutch low-voltage grid assuming a 100% penetration scenario of electric vehicles, heat pumps, and photovoltaics in the households validates that the proposed model can resolve the network issues while not affecting user comfort.
