INTRODUCTION

Smart microgrid helps us to store and distribute

the renewable energy. It is modern, small scale

version of centralized electricity system. Like

the bulk power grid,smart microgrids

distribute and regulate the flow of electricity to

consumers.

View of Smart Microgrid

5

BACKGROUND

The Main Campus of the Illinois Institute of

Technology in Chicago was experiencing

one to three major outages per year, each

costing an estimated,$520,000 in restoration

expenses. The remedy would be extremely

expensive.

6

MODE OF OPERATIONS

There are three modes of operations for

Smart Microgrid:

•Grid Connected Mode

•Island Connected Mode

•Emergency Mode

7

GRID CONNECTED

MODE

In this mode grid is directly connected to

supply. It determines the appropriate set

points for individual generators, storage

elements, and loads in the microgrid. Its also

supply constant power mode for all DER

(Distribute energy resource).

8

ISLAND CONNECTED

MODE

This mode having two DER. It performing

operation in MASTER/SLAVE mode.

DER 1: Transfer supply to master mode.

DER2: Transfer supply to slave mode.

9

ISLAND OPRATION IN

MASTER MODE

When island connected to the master mode

its behave like a master controller. It

provides the interface between the system

controller and individual load generator.

10

ISLAND OPRATION IN

SLAVE MODE

When island connected to the slave mode its

behave like a slave controller .

There are four type of slave controller:

Local Generators

Storage devices

Loads

Microgrid switch or breaker11

Emergency Mode

In this mode the response will depend

upon the need of supply system. The response

can include: changing generator conditions,

reducing load, or actually disconnecting from

the supply system.

IDEAL COMPONENT OF

MICROGRID

Mainly there are two component of Smart Microgrid:

1: Distributed Energy Resources

I. Generation

II. Storage

2: Flexible Loads

I. Metering

II. Control

III. Protection

IV. Communication

14

Distributed Energy

Generation

Distributed energy generates electricity

from many small energy sources, such as

fossil fuel, nuclear, large solar power plants

and hydropower plants. Distributed generation

allow collection of energy from many sources

and may give lower environmental impacts

and improved security of supply.

15

DISTRIBUTION OF

ENERGY

16

DISTRIBUTED ENERGY

STORAGE

Grid energy storage send excess electricity

over the electricity transmission grid to

temporary electricity storage sites that

subsequently become energy suppliers when

electricity demand is greater.

17

FLEXIBLE LOADS

The identification and appropriate control

of flexible loads can be employed to

balance energy and demand. The system to

meet the demand not only by changing the

generated energy but also by controlling the

load when necessary.

18

WORKING

A microgrid is a localized grouping of

electricity generation, energy storage,

and loads that normally operates

connected to a traditional centralized

grid (macrogrid). This single point of

common coupling with the macrogrid

can be disconnected. The microgrid

can then function autonomously.

19

APPLICATIONS

Communication standards and protocols.

Large scale energy storage.

Participation in energy markets.

Distributed Generation and Alternative

energy sources.

Demand Response and Dynamic Pricing

USE OF MICROGRID

21

MICROGRID FEATURES

ADVANTAGES

Locally secure.

Differentiation of electrical service possible.

Allow easier integration of renewable.

Increases reliability

DISADVANTAGES

Can be expensive

Work yet to be done in controls, operation and protection.

22

Future scopeThe microgrid structure makes it a viable

platform for large entities to reduce energy

costs and generate revenue through the sale

of energy during periods of peak demand.

Additionally, microgrids can efficiently and

effectively provide "off-grid" areas with

regular access to electricity as well as "keep

the lights on" in times of crisis for critical

applications like a hospital.
