This document outlines a proposed microgrid project for CPFL. It begins with an agenda and overview of how microgrids work, including definitions, categories, components, and benefits. It then discusses example microgrid projects around the world and proposes a scope for CPFL's project, including studying cybersecurity, pilot projects, data analysis, and testing intelligent controllers. The proposed project would benchmark testbeds and applications, set up a laboratory, and demonstrate features like automatic isolation. It provides guidelines and recommends covering areas like modeling, control systems, energy storage, and network optimization. Finally, it presents a schedule and overview of four proposed test sites for the project.

4. Microgrid definitions and how they work
Fonte: EEonline; The Macro View of Microgrids: Addressing Complex Trends and Challenges, March-2018
Some apply a size-based definition,
suggesting a microgrid has to be below 50
MW. But a more functional definition that has
stood the test of time is the one provided by
Steve Bossart, Senior Energy Analyst, at the
DOE’s National Energy Technology
Laboratory:
“A microgrid is a group of interconnected
loads and distributed energy resources
within clearly defined electrical boundaries
that acts as a single controllable entity with
respect to the grid. A microgrid can connect
and disconnect from the grid to enable it to
operate in both grid-connected or island-
mode.”
Or
“A microgrid is a local energy grid with
control capability, which means it can
disconnect from the traditional grid and
operate autonomously - simple definition
(US Department of Energy)”
What constitutes a microgrid? How they work?

5. Microgrids categories
Most micro grids can be further described by one of five categories
• Off-grid micro grids including islands, remote sites, and other micro grid systems not connected
to a local utility network.
• Campus micro grids that are fully interconnected with a local utility grid, but can also maintain
some level of service in isolation from the grid, such as during a utility outage. Typical examples
serve university and corporate campuses, prisons, and military bases.
• Community micro grids that are integrated into utility networks. Such microgrids serve multiple
customers or services within a community, generally to provide resilient power for vital community
assets.
• District Energy micro grids that provide electricity as well as thermal energy for heating (and
cooling) of multiple facilities.
• Nano grids comprised of the smallest discrete network units with the capability to operate
independently. A nano grid can be defined as a single building or a single energy domain.
• It is a small-scale power supply network that is
designed to provide power for a small community.
• It enables local power generation for local loads.
• It comprises of various small power generating
sources that makes it highly flexible and efficient.

13. Motivation – why do a microgrid Project – which chalenges faces?
IN the new scenarios, megatrends, climate changes, resource scarcity, asset aging, massive penetration of
DISTRIBUTED ENERGY RESOURCES (DER), INCLUDING DISTRIBUTED GENERATION (DG) and distributed
storage (DS), a microgrid project is a great opportunity to plan, execute, implement and operate including
diferente kind of Energy sources and Storage, how to control and operate it analyse costs of fuel and of the
operation.
A microgrid Project is a great oportunity to antecipate trends, answer questions and helps defines if it is a
treat or an opportunity to CPFL in technical, regulatory and comercial aspects and and how to deal with this
issue.
Microgrid Project
Objective – what are the objectives?
The objective is study and modelling operation of a microgrid with different sources, including storages,
not only batteries, adavanced Technologies and systems control, comparation between AC na DC modes,
cost evaluation, benckmarks, new models of operation, safety aspects (technical and cyber) and
forecasting & curtailment, and/or demand response.
