The world is changing
Some facts

SLIDE 6
The world is changing (quickly)
The future will be a full electric world in which nearly all applications in daily life and at home will be electrical
Photovoltaic (PV)
will be standard on single- and double-family houses
Directive 2010/31/EU – Nearly zero-energy buildings (NZEB) from 2020 on Today PV is the cheapest way to fulfill this directive
Smart Grids
Buildings will be connected with the grid
By the replacement of nuclear and fossil fuel driven power plants with lots of volatile renewable generators the connection of all players in grid becomes mandatory
E-Mobility
Future cars will be electrical
All car manufacturers are designing their new cars as electric vehicles
Heating
Heating will be electrical
From 2025 on heating systems based on combustion will be forbidden

Home Energy Management System
HEMS manages and optimises the energy flows in the building and the exchanges with EVs and grid

From a Grid perspective

SLIDE 11
From a Grid perspective
Make match consumption and production
11
- The dominant model is to adapt the production to the consumption. This is done
with fossil energy production means such as gas.
- Another option is to add some flexibility on the consumer side. This can be done
by connecting a lot of buildings having flexible loads, local production and storage in a virtual power plant.
- One way to make the grid smart is to send tariff information to the HEMS of all the
buildings in order to make them react.
- Low price means overproduction => consume
- High price means overconsumption => stop consuming or produce

Home Energy Management System
HEMS is the brain in the building that is connected to all components

SLIDE 14
Home Energy Management System
HEMS is in charge of finding the optimum in energy consumption of the building
14
- Collects local information such as consumption and production
- Makes prediction based on weather forecast for PV production and consumption
based on self learning
- By using algorithms, controls the battery charge and discharge
- Controls the electric car to avoid black out
- Makes proposals/recommendations to big consumers such as electric vehicle or
heat pump in order to save money or used locally (PV) produced energy
- Get dynamic tariff information from the grid (utility) and take them into account in
the optimization algorithms and give them to the main consumers
- HEMS can control directly some devices and acts as an agent for others such as
EV or heat pump…

SLIDE 16
Home Energy Management System
Main benefits
16
- Benefits for utilities and grid operators
- Additional flexibility that saves operation of fossil production means
- They will help to enable the introduction of renewable energies and electric
vehicle in the ecosystem
- Benefits for the end-user
- Increase of self consumption and autarky level (from 20 to 80%)
- Money saving and visibility
- Become an actor of energy transition
- Benefits for citizens and planets
- Increase the share of renewables and contribute to reduce CO2 emissions
