Commercial complexes require stable power for diverse critical loads, yet grid fluctuations and outages can disrupt operations and increase energy costs. Integrating solar, energy storage, and diesel generation through a unified microgrid can improve power reliability while enabling more efficient energy management.
Building a Stable and Efficient Multi-Energy Power Supply System for Commercial Complexes
In some parts of Africa, commercial complexes, hotel complexes, and large-scale commercial projects commonly face issues with insufficient grid power supply stability. Frequent power outages and voltage fluctuations not only disrupt daily operations but can also cause critical facilities—such as refrigeration, lighting, elevators, and food service—to shut down, directly impacting customer experience and operational revenue.
To ensure business continuity, many projects have installed photovoltaic, energy storage, and diesel power generation systems simultaneously. However, because these systems operate independently without unified dispatch or coordinated control, the utilization rate of renewable energy remains low, diesel engines run for extended periods, and overall energy efficiency is difficult to improve.
To address the multi-energy management needs of commercial complexes, YUNT offers a PV-Storage-Diesel Microgrid System Integration Solution. Through a unified energy dispatch platform, this solution enables the coordinated operation of PV, energy storage, grid power, and diesel generators, helping clients build a more stable, economical, and intelligent energy system.
Scenario Requirements: Ensuring Uninterrupted Commercial Operations
Energy systems in commercial complexes typically need to meet the following requirements:
- Continuous and stable power supply despite grid fluctuations;
- Reduced operational energy costs;
- Improved utilization of photovoltaic energy;
- Responding to unexpected power outages to ensure the continuous operation of critical loads.
At the same time, the project involves the coordinated operation of various energy equipment, placing higher demands on system integration capabilities and energy management strategies.
System Solution: Building a Unified Energy Management Platform
Based on the operational characteristics of commercial complexes, YUNT provides integrated services ranging from solution design and equipment integration to on-site commissioning.
Project Integration:
- Mesh-type power conversion system(PCS) clusters;
- STS/ATS rapid switching system;
- Energy storage battery system;
- Photovoltaic power generation systems;
- EMS Energy Management Platform.
Through a unified control architecture, the system enables coordinated management of photovoltaic power, energy storage, utility power, and diesel generation.
The system automatically optimizes operating strategies based on load changes:
During routine operation:
- PV power is prioritized;
- Energy storage is used for peak shaving and valley filling;
- Reduces peak electricity purchase demand.
During grid fluctuations or power outages:
- The static transfer switch(STS) rapidly switches between grid-connected and off-grid modes;
- The PCS maintains stable voltage and frequency;
- Energy storage and diesel generators work together to supply power;
- Ensures the continuous operation of critical loads such as lighting, elevators, air conditioning, and food service facilities.
At the same time, the system supports remote monitoring and intelligent operation and maintenance, helping customers track equipment operating status in real time and improve energy management efficiency.
Project Value: Enhancing Commercial Energy Operations Capabilities
Through the integration of a photovoltaic-storage-diesel microgrid system, the project helps customers achieve unified management of multiple energy sources, improve the utilization efficiency of renewable energy, and reduce diesel engine runtime and overall energy costs.
Compared to traditional backup power models, the system not only strengthens the commercial complex’s ability to ensure power supply stability in the face of grid fluctuations but also improves energy efficiency and operational management standards.
This project fully demonstrates YUNT’s technical capabilities in complex commercial scenarios, multi-energy coordination, and microgrid system integration. It can be widely applied in settings such as hotels, commercial complexes, office parks, and large public buildings, providing stable and reliable integrated energy solutions for overseas commercial clients.
