12 Micro-power station scheme Multifuel Combustion of biomass Thermal energy Evaporator Evaporation and superheat of the working medium Turbine Driven by the vapor of the working medium Mechanical energy Electric-power generator Driven by the steam turbine Electricity Condenser Condensing the workin medium and water heating Heat

13 General energy conversion efficiency Taking into account the loss of individual components, the efficiency of the power station can be expressed as the product of: Theoretical efficiency of Rankine cycle Boiler efficiency Isentropic efficiency of the turbine Overall efficiency of the turbine Efficiency resulting from the power supply to pump power

14 Machinery and equipment in micro CHP Steam turbine Multifuel Capacitor The use of an organic medium The use of technology of hermetic machines and bearings High speed bearings lubricated with an organic medium of the turbine Low emissions of harmful substances into the atmosphere Tight construction Integrated with micro-turbines Evaporator Small size Large surface area for heat exchange Power generator Electric pump Low boiling medium

15 Solar hybrid system

16 Photovoltaic module Top layer Electricity production Solar thermal collector Bottom layer PV cooling Heat production

17 Efficiency The efficiency of the integrated solar system is higher than a sum of its components This is a result of providing optimal work temperature of PV module

18 Ventilation, air-conditiong and heating system

21 SMART GRIDS

22 Definition The integration and application of real-time monitoring, advanced sensing, communications, analytics and control, enabling the dynamic flow of both energy and information to accomodate existing and new forms of supply, delivery and use in a secure, reliable and efficient electric power system from generation source to end-user. Źródło: [1]

23 It is self-healing from power disturbance events Enables active participation of consumers in demand response Operates resiliently against both: physical and cyber attacks Provides quality power that meets 21-st century needs Accomodates all generation and storage options Enables new products, services and markets Optimizes asset utilization and opearting efficiency

24 ICT for Smart Buildings Due to the European Comission Report it is clear that if smart, green bulildings are to become commonplace, that this can only be facilitated by ICT. Buildings provide 40% of energy end-use in the EU. It has been forecoasted that ICT can reduce this level by 15% in the coming years.

25 ICT for Smart Buildings New ICT based Systems would allow peer-to-peer sharing of energy produced through renewable schemes. Intelligent meters would allow households buy and also sell energy. ICT will allow information on energy consumption of every energy-consuming appliance in a building to be provided in real-time, in a user friendly way, thereby empowering citizens to take decisions that lead to energy savings.

26 A need for a new concept of BMS BMS (Building Management System) is a solution that is already present in some buildings. Nevertheless, the is inability to centralize and manage data found within building equipment. Existing buildings are full of technology and communication devices that have been installed ad hold over time.

27 A need for a new concept of BMS These devices, eg.: household devices, computer and Internet connections, security devices, HVAC systems, lighting, tend to operate on different protocol standards. That is why, usually these solutions are non-integrated and managing or monitoring energy usage is difficult.

28 Łukasz Adrian Marta Jabłońska Marcin Janicki Andrzej Klimek Eliza Tkacz Katarzyna Znajdek HOUSE 2020 The concept of a new BMS system will be designed for a House 2020 project. The system will include new challenges for BMS systems: Intelligent meters Prosumers (consumers of energy that can also sell energy) Intelligent household appliances Management of energy consumption

29 Łukasz Adrian Marta Jabłońska Marcin Janicki Andrzej Klimek Eliza Tkacz Katarzyna Znajdek HOUSE 2020 The concept of a new BMS system will be designed for a House 2020 project. The system will include new challenges for BMS systems: The concept will also include the idea of smart grids, making communication among the set of buildings possible. The energy consumption user profile will be analysed and optimized in a way that maximizes the use od Renewable Energy Resources installed in a building or a set of buildings.
