Impact Evaluation of Electric Heat Pump Integration in Rural Distribution Network

With the advancement of electric energy substitution project, many electric heat pumps are connected to rural distribution network, which has different degrees of impact on users. Therefore, this paper proposes evaluation indicators to analyze the impacts of heat pumps to rural distribution network as well as the effects of some control strategies. Firstly, the thermodynamic process and operation characteristics of typical electric heat pump are analyzed. Then the evaluation indicators are introduced and a voltage optimization regulation strategy based on self-regulation of heat pump are evaluated. Finally, the results of case show that the proposed evaluation indicators can effectively reflect the actual situation of the electric energy substitution project in the rural distribution network and the effect of the control strategy.
