Energy storage system integrated with private courtyard electrical plant operation

What is shared electrical energy storage (SES) & shared thermal energy storage?

To mend the research gap, two CHP-SES system modes and design procedures, namely shared electrical energy storage (SEES), and shared thermal energy storage (STES), are proposed. These systems store distributed green power curtailments during the charging process and convert them to available power or heat during the discharging process.

Can shared electrical energy storage and shared thermal energy storage be used in CHP-SES?

Therefore, this paper proposes two CHP-SES design modes involving shared electrical energy storage and shared thermal energy storage, including three system configurations to store distributed green power curtailments during charging processes and convert them to available power or heat during discharging processes.

Which energy storage technologies are available for SES systems?

The available grid-scale energy storage technologies for SES systems include pumped storage hydropower (PSH), compressed air energy storage (CAES), battery energy storage (BES), and thermal energy storage (TES) . The characteristics of each energy storage technology are shown in Table 1.

Why do grid-scale stationary storage systems use LFP technology?

Therefore, for grid-scale stationary storage systems, the SEES system chooses the LFP technology due to its high energy density and cycling performance. The SEES system (using LFP) is a stand-alone SES system that does not exchange materials and energy with the CHP unit.

How efficient is shared energy storage?

Shared energy storages involving shared electrical and thermal modes are proposed. Exergy and economic models are developed to reveal thermo-economic feasibility. Design procedures considering energy flow and capacity constraints are determined. Round-trip exergy efficiencies of proposed modes are 78.98 %, 54.34 %, and 43.36 %.

Can a CHP plant be integrated with a ses system?

Integrating CHP plants with SES systems is a feasible way to recycle distributed green power curtailments while meeting power and heat supply in an energy network. In this work, two CHP-SES design modes (SEES mode, and STES mode) are proposed.
