Currently, the application and optimization of residential energy storage have focused mostly on batteries, with little consideration given to other forms of energy storage. Based on the load characteristics of users, this paper proposes a composite energy system that applies solar, electric, thermal and other types of energy.
Electrical energy storage The electrical energy storage (EES) system can store electrical energy in the form of electricity or a magnetic field. This type of storage system can store a significant amount of energy for short-term usage. Super-capacitor and superconducting magnetic energy storage are examples of EES systems.
Consequently, the integration of RES into the power system can pose an adverse impact and reduce the reliability of the user service. To this extent, Energy Storage Systems (ESS) are nowadays integrated into the power system to smooth the amount of bulk power generation and mostly, to mitigate the intermittency of RES.
Regarding environmental performance, the addition of energy storage equipment leads to an increase in system carbon emissions to varying degrees, among which the increase of the BESS is the smallest. In terms of energy performance, the HESS has the highest PSR and can consume more PV power generation than the BESS and TESS.
