摘要

Promoting the distributed photovoltaic (DPV) joint household battery energy storage system (HBESS) on the rural resident’s house is an important way to reduce carbon emissions and promote the green electricity consumption. It is necessary to guide the rural residents to actively accept DPV-HBESS system and enhance their green electricity consumption by the incentive policies. To explore the better incentive policies to encourage DPV-HBESS diffusion, this paper firstly abstracts DPV-HBESS environment and divides it into three categories, namely DPV, power consumption equipment and power storage equipment. Secondly, we analyze the operation law and power flow of the three types of equipment, then conduct a mathematics measurement model of the residential green electricity consumption space. Thirdly, a system dynamics (SD) model is constructed, which contains multiple equipment subsystems and the dynamics changes of power. Finally, we carry out the comprehensive analysis of residential green electricity consumption space under time-of-use tariffs (TOU), subsidy for renewable energy generation (SREG) and subsidy for green electricity consumption (SGEC). The results show that rural residents are unwilling to deploy the DPV-HBESS without any policy support, however, their willingness to consume green electricity has a positive response under the three incentive policies. The better combination policy should be implemented in two-stage, the initial step is ‘TOU + SREG’ to drive the deployment rate of DPV-HBESS, then the policy of ‘TOU + SGEC’ follow. The research provides a reference for the orderly guidance of the residents to deploy the DPV-HBESS system and participate in green electricity consumption.
