Premises energy management describes the automated management of electric appliances. The objective of the premises energy management system (PEMS) is to provide a value-added service to the PEMS owner and a single interface for the utility through which aggregated grid services can be supplied. This report provides two contributions to existing research: a functional requirement literature review and a simulated PEMS performance analysis.
This report includes a functional requirements literature review and simulation results quantifying the performance of a proposed PEMS. The functional requirements describe the basic functions of the system and subsequent components of the system. A simulation test bed was developed to simulate example residential premises. The simulation results showed the following:
- An average energy and cost reduction of 18% (14.21 kWh and 2.84 kW) per day due to the programmable thermostat function
- Average demand-response service time energy
- Average power demand reductions of 41% (5.53 kWh and 1.84 kW) due to the demand response appliance rescheduling during a demand-response event (61% with the stationary battery: 8.27 kWh and 2.76 kW)
In general, these results imply that PEMS saves the PEMS owner money and provides automated demand-response performance.
