Customized Integrated Solution For Solar Power Station

Project Name: 400 MW Solar PV Independent Power Plant Project

Location: A desert region in the Middle East

Key Challenges: Extremely high temperatures, dusty environments, DC-side transmission losses, system efficiency optimization, and initial investment control

Solution Provider:TSTY Electric Co.,LTD

I. Project Background and Targeted Requirements Analysis

In response to the global goal of carbon neutrality, a 400 MW ultra-large photovoltaic power station project has officially commenced in the desert region of the Middle East. While the region boasts abundant sunshine, temperatures exceeding 45°C daily and frequent sandstorms pose extreme challenges to the reliability of power equipment. The project owner is highly concerned about the plant's levelized cost of electricity (LCO) and requires a solution that excels in the following areas:

Ultimate Efficiency: Maximize system power generation, particularly addressing losses associated with long-distance DC transmission.

Rugged and Reliable: The equipment must withstand harsh environments characterized by high temperature, humidity, and corrosion, ensuring a 25-year lifespan.

Economical and Efficient: While maintaining performance, the initial investment is optimized and ongoing costs are reduced through intelligent operations and maintenance.

II. Core Solution: TSTY-PV-Integrated Intelligent Integrated Substation

After in-depth technical evaluation, TSTY customized the PV-Integrated series of intelligent integrated substations specifically for this project. This solution deeply integrates a high-efficiency boost converter with a medium-sized box-type substation to form a standardized photovoltaic power generation unit. Based on user needs, this all-in-one product integrates a PCS converter, a boost transformer, a protective switch, and auxiliary equipment such as networking communications, auxiliary power, cooling, and fire protection. Its compact structure, rational layout, and small footprint reduce auxiliary equipment costs, facilitate on-site construction, and reduce workload. During operation, the integrated unit demonstrated excellent performance, rapidly responding to grid dispatch commands and precisely controlling bidirectional power flows, ensuring efficient coordination between the energy storage system and the grid and effectively improving power quality.
