Peak Valley arbitrage and demand management
Under the background of the gradual opening up of the power market and the in-depth promotion of the reform of the power system, the peak-valley arbitrage and demand management of solar energy + energy storage system have become an important means for enterprises to obtain additional earnings. This paper will introduce the operation mechanism of this profit model and the economic benefits it brings to the enterprise in detail.
Peak-valley arbitrage
Peak valley arbitrage refers to the profit model of charging the energy storage system during the low peak period of power demand (low electricity price) and discharging during the peak period (high electricity price), so as to earn the difference in electricity price. This model can not only help enterprises reduce the cost of electricity, but also bring additional benefits to enterprises.
Operation mechanism
In the low price of electricity, the energy storage system from the grid or sales company to buy low-price electric energy for charging; At times of peak electricity prices, the energy storage system supplies power to the load, reducing the need to buy high-priced electricity from the grid. In this way, enterprises can realize the transfer of peak load and obtain benefits from peak and valley electricity prices.
Economic Benefits
Taking a 6MWh industrial and commercial energy storage project in Zhejiang Province as an example, according to the charge and discharge depth of 90%, charge and discharge efficiency of 92%, running 300 days a year, charge and discharge twice a day, the total annual peak and valley arbitrage income is 1,673,200 yuan.
Demand management
Demand management refers to the profit model of further reducing energy costs by optimizing the charge and discharge strategy of the energy storage system to reduce the maximum electricity and electricity expenditure of the enterprise.
Operation mechanism
The energy storage system can monitor the electricity consumption of the enterprise in real time, and make intelligent adjustment to the charge and discharge strategy according to the fluctuation of the electricity price. During peak hours, the energy storage system can reduce the instantaneous load, control the maximum demand, and effectively reduce the electricity bill.
Economic Benefits
Energy storage systems have achieved remarkable results in demand management in manufacturing, commercial buildings, data centers, cold chain logistics and other industries. By flexibly regulating electricity demand during peak hours, these industries can significantly reduce demand loads and cut electricity bills.
Integration of diversified income models
With the gradual opening of the electricity market, the combination of demand management and virtual power plant (VPP) will become more and more close. In the future, enterprises can not only optimize electricity costs through energy storage systems and demand management, but also participate in power market transactions through virtual power plant technology, and obtain more considerable economic returns.
conclusion
As a profit model of solar energy storage system, peak-valley arbitrage and demand management can not only help enterprises reduce electricity costs, but also bring additional benefits to enterprises. With the continuous deepening of electricity market reform, this model is expected to be more widely used and promoted in the future, and become an important way for enterprises to break the electricity tariff.
