Adding more renewable energy into the grid presents technical and operational challenges for utilities and grid operators. Solar and wind power, for example, can only be generated at certain hours of the day and night, and weather conditions have a big impact on their production rates. Since an electric grid works best when there is a balance of supply and demand, grid operators have to figure out how to make up for any shortfall or surge of renewable energy that could happen at any time. Power plants that use coal, natural gas and nuclear, on the other hand, can produce a steady stream of power.

The second part of the Los Alamos Department of Public Utilities NEDO project, is a 2,418 square foot “Smart House”, and pairs the solar system by Kyocera with a lithium-ion battery system, a heat pump storage unit, and sensors and communication equipment. The idea is to figure out how to operate all this equipment to meet the energy demand of the home and respond to any requests from the utility or grid operator to use the solar electricity for balancing the grid.

The demonstration house is equipped with 3.4kW photovoltaic, a 24kWh battery, a home energy management system (HEMS), smart equipment and appliances for optimized power consumption, smart meters and Heat Water Storage (heat pump) systems.

The HEMS system will allow the home to compare electricity prices and determine the most cost effective use and source of power (PV, battery, LAC grid) at any given moment of the day.

Key objectives of the Smart House are to demonstrate control between the micro-Energy Management System being developed by the DPU-NEDO project and the smart house energy management system (using price signals), demonstration of the HEMS systems ability to operate the smart house equipment under varied conditions.
