Home Energy Management Systems (HEMS) are solutions incorporating products and services for monitoring, analysis, visualization and control of energy in the home. This definition includes demand response and supply response programs, home automation services, personal energy management, data analysis and visualization, auditing, and related security services.
Numerous HEMS pilots, projects and products have been developed previous to Wizee. The core differentiator of the current R&D effort will be a focus on “Future HEMS”, introducing the transactive energy model as the means by which the integration of renewables will be achieved. Research results will be grounded in actual user data collected from real building environments, as well as data simulation. The investigation will go beyond system optimization which is well studied, but on machine learning of user behavioural patterns, and the development of forecasting and control algorithms trained on home energy data.
INNOVATION AT THE GRID EDGE
Ideally, flexible HEMS solutions improve the energy efficiency of residential housing, through smart, self-learning of consumer lifestyle, to create a sense of well-being while conserving energy. In addition to enabling consumers control electrical appliances and electric or boiler-based heating, integration with the smart metering system, should allow aggregation of consumption information from multiple sources, for the balancing of energy supply and peak shaving, with direct economic benefits for the end-user. Advanced features should also drive benefits to energy retailers striving to manage energy demand and supply through consumer engagement and demand response / supply response programs as well as Virtual Power Plant solutions, solar feed-in management, and home energy storage.
The Wizee project will build on these concepts to develop operational strategies which enable the optimization of benefits (economic, environmental, comfort, convenience) for the prosumer. The main research objectives are to:
1. Investigate how the complexity of optimally managing such a prosumer environment can be achieved with minimal user intervention (adaptive forecast of consumption and switch-on times optimizing switch plans for loads as well as for storage)
2. Explore the trade-offs between home-based and mixed home- and cloud-based deployments
3. Provide guidance on the possible use of the model to support energy management in nanogrids and (neighbourhood and district) microgrids
Core to Wizee’s foundation is Smart Metering data coming from Advanced Metering Infrastructure (AMI) deployments, the platform for all Smart-Grid value applications and demand response solutions. The project will therefore also contribute to the cost-benefit discussion of smart-metering infrastructure. This becomes essential when electricity prices become dynamic. For example, flexible residential appliances such as boilers can be switched for energy storage during periods of excess supply. The core intellectual property developed under Wizee will be the intelligence engine underlying the Home Energy Management System, and will be a software development of applications to overlay the hardware & communications of AMI and Home Area Networks.
Landis+Gyr and the iHomeLab at the University of Luzern, have participated together in numerous R&D projects in the previous decades. The WIZee project continues our long tradition of collaboration and joint innovation with practical business- and consumer- applications in mind.
The team of the iHomeLab, led by Prof. Alexander Klapproth, explores generally how to lower and flexibilize the energy consumption of buildings and how to allow elderly people to live longer in their own homes thanks to intelligent housing. The results of the research projects are presented in the iHomeLab Visitor Center and explained in a comprehensive way.
Landis+Gyr is the largest global player in smart metering with one of the broadest portfolios in the industry. Our products, solutions and services empower grid operators with the data necessary to make informed decisions about energy usage, to meet the worldwide energy challenges of today and tomorrow.
The Wizee project shall broaden Landis+Gyr capabilities in the area of consumer intelligence, where we invest in technology and solutions allowing for greater engagement with utility customers through shared insights and control capabilities. Therefore, Landis+Gyr sees the Wizee project as a core strategic platform for future long term growth in the smart energy, smart-grid and smart-home sectors.
