Analysis Of Business Model And Investment Income Of User Side Energy Storage

Energy storage system can smooth the load curve of power grid and promote the consumption of new energy.In recent years,the application field of energy storage has gradually shifted from the power supply side and the grid side to the user side,and the user side energy storage business model has become a research hotspot.Due to its high cost,long payback period,small capacity and decentralized configuration,energy storage on the user side can not independently participate in the power market and new energy consumption to make profits.Therefore,it is necessary to seek a new business model to improve its economy.On the basis of the existing research,considering the energy storage convergence potential and sharing concept,the user side energy storage business model is divided into independent operation mode,unified operation mode and shared energy storage mode.On the basis of peak valley arbitrage,focus on the new energy consumption value generated by the accumulation of user side energy storage,expand profit channels;improve the utilization rate of user side energy storage and reduce investment costs through energy storage sharing.According to the independent operation mode,considering the economic and technical parameters of different energy storage batteries,the investment and income model of user side energy storage in the life cycle is established.The economic indicators such as net income,payback period and return rate of investment are introduced to verify the feasibility of user side energy storage investment in the life cycle,and the impact of battery cost and peak valley price difference on user side energy storage economy is analyzed.In this paper,a practical application of a unified operation mode virtual power plant mode is studied.The virtual power plant is composed of thermal power,wind power and user side energy storage,W·hich controls the charging and discharging of user side energy storage group to meet the peak valley arbitrage of users and absorb wind power at the same time.The compensation function of energy storage control right transfer is designed to stimulate the users to transfer the energy storage control right to the virtual power plant,and the benefit optimization model of the virtual power plant using the user side energy storage control right is established to maximize the operation benefit of the virtual power plant.The simulation results show that the unified control of user side energy storage by virtual power plant can promote wind power consumption,and improve the benefits of virtual power plant and users.This paper studies the practical application of a shared energy storage business modelthe optimal allocation of participants in the cloud energy storage business model.This paper introduces the participants and operation mode of cloud energy storage mode,designs the leasing price function of cloud energy storage,and establishes the optimal allocation model of participants of cloud energy storage based on bi level programming model.The inner layer is the user layer of cloud energy storage,with the minimum power consumption cost as the goal,the user optimal allocation model is established to solve the cloud energy storage capacity and charging and discharging power leased by users,and analyze the investment cost and energy storage income;the outer layer is the operator layer of cloud energy storage,W·hich integrates the optimization results of all users in the inner layer,and establishes the operator optimal allocation model with the minimum operation cost as the goal,so as to solve the problem Understand the operator’s actual energy storage capacity configuration and charging and discharging power.The simulation results show that the cloud energy storage business model can effectively reduce the user’s electricity cost,and the cloud energy storage operators can reduce the energy storage capacity allocation based on the complementary characteristics of user’s energy consumption,so as to obtain benefits.Diversified business model can provide users with channels to reduce the cost of energy storage investment,expand the way of energy storage profit,improve the utilization rate of energy storage equipment,promote new energy consumption,and facilitate the market-oriented development of energy storage on the user side.
