Some industrial parks in China have completed the construction of green composite energy network and obtained the green building identification certification. However, after several years of operation, their renewable energy system has room to be updated. After combing the domestic and foreign studies, the current situation and prospects of the energy system in an industrial park in Tianjin, China are analyzed. Eight strategies were proposed from the three aspects of expanding photovoltaic area, upgrading photovoltaic equipment and improving management. The energy output, economic impact and environmental effects were calculated for each scenario. Results displayed that using the photovoltaic system upgrading strategy proposed in this paper, the renewable energy use of the integrated energy park can be effectively improved and enhance its demonstration significance in the whole society.
