DER INTEGRATION
VPP PILOT PROJECT
The Low-Voltage Virtual Power Plant (Low-Voltage VPP) Project
Project Overview:
The Provincial Electricity Authority (PEA) and Finergy Co., Ltd. have jointly studied and implemented the Low-Voltage Virtual Power Plant (VPP) Project under a Memorandum of Understanding (MOU)
Project Objective:
- To explore and develop approaches, methodologies, and technological tools for enhancing the management efficiency, reliability, and flexibility of the low-voltage distribution network
- To address the growing deployment of Distributed Energy Resources (DERs), such as solar rooftop, battery, and electric vehicles (EVs)
- To align with Thailand’s national policy on achieving carbon neutrality
Project Location and Scope:
- The project is located in Pattaya City, Chonburi Province, within PEA's low-voltage network
- It includes 8 prosumers (consumers with solar rooftops), 1 EV, 1 community battery, and 11 consumers, all connected under the same distribution transformer

Low-Voltage VPP (VPP/Aggregator Level 1) Functionality:
- Serves as a local management system
- Manages active components such as solar rooftop and community battery within the low-voltage network under a single distribution transformer
- Aims for voltage and load management
Project Objective:
- The Low-Voltage VPP is a software-based platform designed for comprehensive network management
- Includes monitoring and optimization/control functions such as dynamic curtailment of prosumers, community battery integration, and hybrid solutions
Contribution: This approach contributes to enhanced grid flexibility and enables the system to accommodate the growing penetration of DERs
VPP/Aggregator Level 1
A VPP/Aggregator Level 1, which typically manages DERs at the local or distribution transformer level (e.g., solar rooftop, batteries, EVs)
VPP/Aggregator Level 2 (Future)
A VPP/Aggregator Level 2 is an advanced, centralized software platform that aggregates and coordinates multiple DERs across wider areas or multiple systems. By providing orchestration functions-such as real-time coordination, prioritization, and control of DER operations. It enhances grid flexibility, supports system stability, and enables more efficient use of DERs
