Customer Challenge

Optimizing power generation efficiency by accurately tracking the sun as it moves across the sky

Solution

Yokogawa’s STARDOM controller accurately calculates the position of the sun and precisely controls the actuators that keep the solar pannels properly aligned with the sun.

Enabling Technologies

STARDOM Controller

The Stardom RTU controller uses the Solar Position Algorithm of the National Renewable Energy Laboratory of the United States Department of Energy for single- and dual-axis tracking and positioning, and offers an inverter interface via Modbus TCP as well as DNP3 and Modbus RS interface options.

Collaborative Information Server (CI Server)

Yokogawa CI Server allows immediate improvement to production efficiency through digital transformation and reduction of operational maintenance whilst building a digital transformation framework.

PRM Plant Resource Manager

Plant Resource Manager (PRM) makes predictive maintenance easy. Early detection of system and device malfunctions helps prevent catastrophic failures.

CENTUM VP Distributed Control System

The CENTUM VP DCS secures interruption-free “uptime only” plant performance for optimal productivity and profitability in the renewable energy field.

Customer Challenge

Customer Challenge

Large solar fields must be managed reliably and efficiently

Solution

Yokogawa’s solutions can remotely configure the solar tracking controllers and obtain the detailed performance and status information needed to reliably and efficiently manage a large field of solar panels. 

Enabling Technologies

Collaborative Information Server (CI Server)

Yokogawa CI Server allows immediate improvement to production efficiency through digital transformation and reduction of operational maintenance whilst building a digital transformation framework. The use of peer to peer communications reduces the communications load for the SCADA system.

Power Plant Controller (PPC)

Delivers synchronized power control with PV ramp smoothing, output stabilization, and energy shifting to maintain grid reliability. Reduces voltage and frequency disturbances resulting from solar variability. 

 

Customer Challenge

Hybrid plants that combine solar, wind, and BESS are difficult to operate without a unified control system. Independent subsystems create unstable power delivery, inefficient battery dispatch, and challenges in meeting grid-code requirements. Operators risk increased curtailment, performance losses, and reduced reliability if they cannot coordinate generation and storage through a single, intelligent controller.

Solution

A PPC integrated with BESS provides instantaneous support during sudden drops in renewable generation by injecting power from the battery, maintaining frequency and voltage stability. Through intelligent State of Charge (SoC) management, coordinated dispatch, and strict ramp-rate control, the system ensures smooth, predictable, and compliant power delivery to the grid—even under highly variable operating conditions.

Enabling Technologies

Power Plant Controller (PPC)

Stabilize the power supply by coordinating and dispatching generation and storage assets in real time to compensate for sudden load changes. With an advanced system that smooths out oscillations, preventing dangerous flickering and ensuring consistent performance.
