Economic Efficiency Evaluation of Distributed Photovoltaic-Energy Storage Hybrid System Based on the Dynamic Load Changhui Yang, Tianyi Sun

Abstract

Based on the dynamic load of the client and the dynamic output power of the generator, this paper establishes the economic efficiency evaluation model of the distributed photovoltaic-energy storage hybrid system (DPV-ES), quantitatively analyzes the system by the carbon trading income, and considers the depreciation tax-deduction benefit and residual net income in the model. In the empirical case, this paper studies the cost, benefit, net present value (NPV), and payback period (PBP), and conducts sensitivity analysis for six types of policy variables. At the same time, the Multi-factors influence on the economic benefits of the system is studied. According to the empirical results, the corresponding policy recommendations are given for users and governments.

Keywords DPV-ES, Carbon emissions trading, PBP, Policy variables, Subsidy
