Introduction
-No significant change in centrally controlled structure of
Power Electrical Grids for last century.
- Centralized structure and distributed structure

4
Introduction
The Future of Global Energy / 3D’s
● Decarbonize
● Decentralize
● Democratize

5
What is a microgrid ?
A Microgrid is a scaled down version of the
centralized power system that generates,
distributes, and regulates the flow of
electricity.

6
What is Microgrid?
● Small-scale power supply network.
● Local power generation for local loads.
● Highly flexible and efficient.
● Connected to both the local generating
units and the utility.
● Excess power can be sold to the utility grid.
● Size may vary.

7
Advantages of microgrids ?
● Improvements in local energy distributions
● Increasing power reliability
● Financial benefits for both consumer and utility
● Makes utility grid more resilience
● Environment friendly green concept.

8
Drawbacks of current microgrid systems ?
● Voltage, frequency and power quality must be
considered and controlled to acceptable
standards.
● High installation cost
● Standards are not yet available for addressing
operation and protection issues.
● Resynchronization with the utility grid is
difficult.
● Microgrid protection

Objectives
Main objective
- To design and develop multi-agent controlled micro grid
with multiple agents for distributed energy sources
which interact each other and work as an integrated
system.
Specific objectives
- To propose control algorithms, communication
protocols and data collection patterns
- To develop an energy management system based on
MAS.

10
Methodology
- Conduct a detailed research and study on current
exiting designs and concepts
- Exploring components, tools related to the system
design requirements.
- Define the control and network requirements for the
system
- Designing and implementing the agents and develop
internal wireless communication.
- Validate the proposed system in a test-bed

11
What is an Agent ?
- A software designed in a computer system
- An agent can perform,
* Autonomous
* Logical
* Predefined
actions to achieve design objectives of a system.
- An agent has four basic characteristics
* Controlling
* Learning
* Optimizing
* Reasoning

12
What is Multi Agent Concept ?
An MAS is a software based computer system
that is situated in some environment, and that is
capable of taking autonomous action in this
environment in order to meet its design
objectives.
Characteristics of a multi agent system
• Autonomy
• Reactivity
• Proactiveness
• Social ability

Micro-grid Grid Outage Management using Multi Agent Systems
- Use Multi-Agent concept for Energy management in
Microgrids
- Dynamic model considering the intermittent nature of DES
and Loads
- Simulation of the model is developed
Research Gap
- Dynamic model developed only for solar pv source and
loads.
- Centralized structure
- No communication between Agents

Distributed Optimization of Solar Micro-grid using Multi Agent
Reinforcement Learning
- Use Multi-Agent concept for Energy management in Solar PV
based micro grid
- The agent can reason, control,learn, optimize and coordinate
with other agents
Research Gap
- Model developed for only 2 Agents
- Less complexity of the considered problem
- Only proposing the concept - no model developed.
