Hari Listrik NasionalJakarta Convention Centre (JCC) 9-11 Oktober 2019

Outline

• Smart Grid introduction

• BPPT Smart Grid Program

• Fast EV Charger Development

• Smart Grid Application for EV

What it is Smart Grid

• Electrical System Trends :• Renewable Energy growth especially from PV. Rooftop PV + Energy storage system can disrupt the

electricity market (Prosumer Era)• Implementation of IoT devices for measurement, monitoring dan control (smartmeter, etc) and

Digital substation• Tariff variation and demand response• IT implementation for Electrical System Big Data Analysis, Asset Management dan cybersecurity

• Motivation for Smart Grid :

• Desire to make the Grid smarter, safer, reliable and more cost-effecive using advanced sensors, communication technologies and distributed computing.

What’s A Smart Grid?

Integrated Maintenance

Higher asset utilization and management

Vehicle-to-Grid

Better integration of plug-in electric vehicles

Renewable Energy Integration

Ensuring reliability as uncertainty and variability increase

Key Applications

Speeding up Maturation of Feed-in-Tariff (FIT) scheme

A promotional event for new technologies on the RDD&U FIT and other incentives

Increasing Savings,Reliability, and Power Quality

Two-way information flow allows adjustments on both of the supply and the consumer side

Accelerating Smart Energy Tech Adoption

Increasing RE penetration and EV

Key Benefits

Information Management System

Collection and processing, analysis, integration, improved interfaces, information security.

Transmission and Distribution Technology

Capturing renewable production and delivering it when transmission capacity is available, relieving congestion, deferring transformer upgrades in response to peak load growth, etc.

Sensing and Measurement

Smart meter, Meter Reading System, Phasor Measurement Units.

Renewable Energy and EV

• Realtime monitoring energy transaction between 2 Charging Station and 100 kWp Rooftop PV • There are 2 PV Sources for EV Charger :

• 5 kWp direct connection at charging station canopy• 100 kWp at building rooftop

• When the plug is connected to the EV, SCADA Smartgrid will detect and record the energy transaction

• The System can be Expanded into poin to poin energy transaction

Architecture

Charging Profile

• By setting the PV inverter , PV power can be set as main power

• EV charger will communicate with EV to collect battery SoC and other EV data

• When SoC battery reach 80%, charging process automatically stop. If we want to charge full to 100% , use manual mode.

Conclusion

▪ BPPT already start to make model for EV charger monitoring system and EV energy transaction from renewable energy source

▪ In the Prosumer era, poin to poin energy transaction will be popular. The blockchain can be implemented

▪ New bussinees model, tariff must be prepared for next EV era

▪ Smartgrid give solution for providing reliable power supply infrastructure for EV

Micro Grid Definition

• A microgrid is a self-sufficient energy system that serves a discrete geographic footprint, such as a college campus, hospital complex, business center, or neighborhood.

• Within microgrids are one or more kinds of distributed energy (solar panels, wind turbines, combined heat & power, generators) that produce its power. In addition, many newer microgrids contain energy storage, typically from batteries. Some also now have electric vehicle charging stations. nterconnected to nearby buildings, the microgrid provides electricity and possibly heat and cooling for its customers, delivered via sophisticated software and control systems.
