How is ESS Energy charge-saving revenue calculated?
The ESS energy charge-saving revenue is calculated by multiplying the ESS charging and discharging amounts by the electricity rate unit price, assuming that it is actually operated using the operation plan values simulated in Sect. 2.2.3.
What is the optimal PV capacity in a convexity graph?
In the case of a convexity graph, where the IRR increases and then decreases, the largest IRR is selected as the optimal PV capacity. In contrast, in the case of a non-convexity graph, the time when the IRR increase rate is the highest is selected as the optimal PV capacity.
What is energy storage system (ESS)?
ESS is a system that can store electrical energy, which can be charged when surplus generation occurs and discharged when stored power is needed. Therefore, it can compensate for the intermittent power output of renewable energy and prevent constructing additional transmission and distribution lines [ 2 ].
How to calculate PV cell and ESS costs?
Subsequently, a method for calculating the PV cell and ESS costs is described. The cost is divided into facility and installation costs. Moreover, the cost is calculated by multiplying the capacity by the unit price, assuming that the cost is proportional to the capacity.
How is ESS initial capacity calculated?
The ESS initial capacity was calculated using the algorithm shown in Fig. 7 to simulate the possibility of peak load reduction. If an optimal solution cannot be found, the peak-shaving test is repeated while increasing the battery capacity; if an optimal solution is found, this solution is selected as the candidate capacity.
What is the peak load pattern of consumer 2?
As shown in Fig. 10, the annual peak load is 4122 kW, higher than 1830 kW, which is 30% of the contract demand, and is advantageous for obtaining peak reduction revenues. As shown in Fig. 11, the workday load pattern of consumer 2 shows a pattern that increases sharply at 9:00 AM and then decreases at 12:00, 15:00, and 20:00.
