 CHAPTER IV

 Block diagram :

This block diagram represent the interaction between a utility grid, grid-connected buildings (both
residential and commercial), and their on-site generation and load management systems, facilitated
by a Grid-Edge Controller (GEB Controller). Here's a detailed explanation of each block:

1. Utility:
This represents the main electrical utility company that generates and supplies electricity to the grid.
It is the primary source of power for all grid-connected systems, including residential and
commercial buildings.

2. Grid:
The grid distributes electricity from the utility to various endpoints, such as residential and
commercial buildings. The grid serves as the intermediary between power generation (utility) and the
end users. In the diagram, the grid is shown interacting with both the GEB controller and the utility.
The grid can operate bidirectionally, meaning it can supply power to users and, in some cases,
receive power generated on-site at the residential or commercial buildings (for example, from solar
panels).

19
3. GEB Controller (Grid-Edge Building Controller):
The GEB controller acts as an interface between the grid and the end-users (residential and
commercial buildings). It manages the energy flow, allowing buildings to operate efficiently with
both grid power and on-site generation.
The controller ensures that electricity is distributed effectively to the buildings' loads, balancing
supply from the grid and any on-site generation sources. It also handles any real-time grid conditions
like demand-response or power fluctuations.
In both residential and commercial applications, the GEB controller plays a key role in maintaining
an efficient energy balance.

4.Managing loads:
It controls when and how power is used by residential and commercial buildings, optimizing energy
consumption and reducing peak demand.

5. On-Site Generation (Residential and Commercial):

This refers to renewable energy sources such as solar panels, wind turbines, or any other local power
generation systems installed on-site in either residential or commercial buildings.
The on-site generation reduces reliance on grid power by generating electricity locally and, if more
energy is produced than consumed, the excess energy can be fed back into the grid.

6. Residential & Commercial Loads:

Loads refer to the energy consumption devices and appliances within the buildings, such as HVAC
systems, lighting, electronics, and other appliances.
The residential and commercial buildings have different load profiles, but both draw power either
from the grid or on-site generation, depending on the real-time energy availability and demand.

7. Bidirectional Power Flow:

The grid is shown as a bidirectional entity, meaning it can provide power to buildings or receive
power from them, especially if the on-site generation produces excess energy. This characteristic is
important in grid-interactive buildings that contribute to the grid's stability by adjusting their energy
use or sending excess power back.
•Buildings can draw power from the grid when on-site generation is insufficient.
•When on-site generation exceeds the load, excess power can be fed back into the grid, which is
common in systems that use renewable energy sources like solar panels.

20
 Overview:

This diagram illustrates how grid-interactive residential and commercial buildings can operate
efficiently with a combination of grid power and on-site generation. The GEB controller manages
this process by balancing the supply and demand, ensuring that energy is distributed effectively. By
incorporating on-site generation, buildings reduce their dependency on the grid, and any surplus
power can be returned to the grid, benefiting both the user and the utility

 Working of Grid interactive efficient residential buildings :

 Grid-interactive efficient residential buildings (GEBs) work by combining energy efficiency,

renewable energy, and smart grid technologies to create a dynamic relationship with the power
grid. The key feature of GEBs is their ability to optimize energy consumption based on real-time
conditions, including electricity demand, availability of renewable energy, and grid stability.
These buildings are equipped with advanced systems such as smart meters, sensors, and
controllers that monitor and adjust energy usage in response to signals from the grid. This
interaction allows the buildings to reduce energy consumption during peak demand hours,
helping to balance the overall electricity supply.
 A crucial component of GEBs is the integration of renewable energy sources like solar panels.
These renewable systems generate electricity that can be used directly by the building or stored
in battery storage systems for later use. When the grid is under stress, the building can reduce its
reliance on grid electricity by drawing from its own energy reserves. Additionally, excess energy
generated by the building can be fed back into the grid, supporting the overall energy network
and potentially earning the homeowner financial incentives.

 HVAC (Heating, Ventilation, and Air Conditioning) System:

In grid-interactive efficient residential buildings, HVAC systems are essential for

maintaining indoor comfort while optimizing energy use. These systems utilize
advanced controls and smart technologies to adjust heating and cooling based on
occupancy and environmental conditions, integrating with renewable energy sources
like solar panels. They help minimize energy consumption by employing strategies
