Does energy storage demand power and capacity?
Fitting curves of the demands of energy storage for different penetration of power systems. Table 8. Energy storage demand power and capacity at 90% confidence level.
What is the relationship between energy storage configuration capacity and total cost?
Relationship curve between energy storage configuration capacity and total cost under different demand response percentages. On the other hand, at the same energy storage capacity, as the demand response percentage of the distribution network increases, the total system cost gradually decreases.
How does demand response affect energy storage?
Demand response can replace the demand for energy storage regulation at a lower cost, effectively reducing the demand for energy storage configuration capacity in the distribution network, reducing the charge and discharge cycles of energy storage to reduce investment and operating maintenance costs, and has better economic benefits.
How does energy storage demand response configuration capacity affect system costs?
As the percentage of energy storage demand response configuration capacity increases, the total costs of the distribution network gradually decrease. Initially, with demand response configuration capacity at 0%, the total system costs are relatively high.
How does demand response affect the cost of electricity?
The cost of purchasing or selling electricity from/to the main grid is influenced by the output of new energy generation units, the demand response, and the output of energy storage. Suppose the coordination between demand response and energy storage is strong.
How does load demand affect stored energy?
As the load demand increases, both the dispatch and capacity of CAES also increase, leading to a rise in stored energy. With a two-times increase in the load demand ( Fig. 9b ), the maximum available energy stored in the CAES extends to 12.5 days (equivalent to 301.7 hours of mean demand).
