Generation-side ESS can store the abandoned wind and solar energy during power-limited hours, and release it during peak load hours, thereby earning profits
On the user-side, the number of charging and discharging cycles of the energy storage system is limited per day, and the battery life may normally be expected to be around 10 years [18].At the
FIGURE 1. Research idea of new power system investment method. The formula for calculating the total investment scale of the source, grid, load, and storage side of the new power system is shown in Eq. 1: T = C + G − L +(W − I) (1) T = C + G − L + ( W − I) ( 1) In the formula, C C is the power supply-side investment.

Energy return on investment. In energy economics and ecological energetics, energy return on investment ( EROI ), also sometimes called energy returned on energy invested ( ERoEI ), is the ratio of the amount of usable energy (the exergy) delivered from a particular energy resource to the amount of exergy used to obtain that energy resource.
Most of them are about how to configure energy storage in the new energy power plants or thermal power plants to realize joint regulation. The energy storage in new energy power plants could effectively improve the renewable energy penetration and the economic benefits by providing high-quality auxiliary services

The Energy Return on Investment (EROI) is the ratio of energy delivered to energy costs. In the case of electricity generation, the EROI entails the comparison of the electricity generated to the amount of primary energy used in the manufacturing, transport, construction, operation, decommissioning, and other life cycle stages of the facility.

Energy return on investment (EROI or sometimes EROEI, with the second E used to refer to the use of energy in the denominator) is the ratio of energy returned from an energy-gathering activity compared to the energy used in that process. In principle, the idea is to see how much energy society invests to get more energy.
