Abstract
This paper presents a novel hierarchical Internet of Things (IoT)-based scheme for Microgrid-Enabled Intelligent Buildings to achieve energy digitalization and automation with a renewable energy self-consumption strategy. Firstly, a hierarchical structure of Microgrid-Enabled Intelligent Buildings is designed to establish a two-dimensional fusion layered architecture for the microgrid to interact with the composite loads of buildings. The building blocks and functions of each layer are defined specifically. Secondly, to achieve transparent information fusion and interactive cooperation between the supply-side and demand-side, a state transition mechanism driven by a combination of time and events is proposed to activate the real-time and mutual response of generation and loads dynamically. Thirdly, based on the above hierarchical fusion structure and data-driven state transition mechanism, a power balance control algorithm driven by a self-consumption strategy is further proposed to achieve the autonomous balance of supply and demand. Finally, the IoT Microgrid Laboratory at Aalborg University is introduced to show how to implement this novel hierarchical IoT-based scheme in a Microgrid-Enabled Intelligent Building, and the power consensus control method based on the state transition mechanism is verified to achieve a renewable energy self-consumption strategy.
Highlights
The use of electricity is an integral need in human society to meet the rising living quality in different countries
Microgrid is one of the key technologies for solving energy and environmental problems, to increase the penetration of renewable energy and to provide high quality electrical energy, which will play an important role in the edge layer of the Energy Internet [1,2,3,4]
The power and the maturity of renewable energy technologies into consideration, building integrated photovoltaic consumption of traditional buildings is mainly supplied by the utility grid, but taking climate (BIPV), wind power generation and power storage systems are widely used in building systems that change and the maturity of renewable energy technologies into consideration, building integrated can be named photovoltaic (BIPV), wind power generation and power storage systems are widely used in building energy storage Intelligent systems (ESS), and typical loads in buildings such as systems can includes be namedDGs, Microgrid-Enabled heating, ventilating and air conditioning systems (HVAC)
Summary
The use of electricity is an integral need in human society to meet the rising living quality in different countries. It needs a large number building, intelligent building realizes thesecurity automation and intelligence of subsystems such of as components to run and produces a great deal of energy consumption, mainly the consumption of equipment, communication, office, air conditioning, security and monitoring The power in buildings is consumed by space heating or cooling, heating, lighting consumption of traditional buildings is mainly supplied by the utility grid, but taking climate change and feeding of domestic electric appliances, where electric vehicles can be included. The power and the maturity of renewable energy technologies into consideration, building integrated photovoltaic consumption of traditional buildings is mainly supplied by the utility grid, but taking climate (BIPV), wind power generation and power storage systems are widely used in building systems that change and the maturity of renewable energy technologies into consideration, building integrated can be named.
