The deployment of energy storage will change the development layout of new energy. This paper expounds the policy requirements for the allocation of energy storage, and proposes two economic calculation models for energy storage allocation based on the levelized cost of electricity and the on-grid electricity price in the operating area.
Figure 1 illustrates how an electricity store would operate. Energy store operation. Demand must always be balanced by generation and / or storage. 1 This is the thermal energy content of the stored energy expressed in terms of the Lower Heating Value.
In order to use storage to fill the deficits in years 29 to 31, it would be necessary to store energy for decades. Studies of shorter periods seriously underestimate the need for storage. Contingency is included in the modelling to allow for variations not seen in this period.
The pumped storage power station (PSPS) is a special power source that has flexible operation modes and multiple functions. With the rapid economic development in China, the energy demand and the peak-valley load difference of the power grid are continuing to increase.
This policy brief considers the role large-scale electricity storage will need to play in a GB electricity system supplied largely by wind and solar. The analysis of the amount and type of storage that will be needed allows for baseload nuclear power or gas with CCS.
It is a tool for power conversion and reserve. At present, the comprehensive efficiency of the PSPS is about 75% (the ratio of power generated to power consumed) in China, which is also called "using 4 degrees to produce 3 degrees”. The PSPS is the best tool for energy storage.
