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

Presenting different kinds of data in such a way that they can be understood at a glance

Solution

Renewable Power Plant Controller

Synchronized high-speed power control, including PV smoothing/ramp control and energy shifting. Mitigates voltage and frequency fluctuations caused by solar intermittency.

 

Customer Challenge

Integrating the various systems and subsystems throughout a plant so as to optimize efficiency and ensure stable operation

Solution

Yokogawa seamlessly integrates the power generation system with subsystems such as the solar collection system and the heat exchange system. This facilitates the monitoring and control of the entire plant, thereby leading to increased efficiency and greater stability.

Enabling Technologies

Renewable Power Plant Controller

Bring clarity and reduce the cost of operations through direct, real-time asset monitoring and optimization that consolidates disparate system controls and visualizations into a single platform.

 

Customer Challenge

Using battery energy management system (BESS) in order to ensure the stable supply of power to the grid even when there is a dip in poer generation

Solution

Yokogawa’s network-based control system with its redundant SCADA helps customer’s stable and profit-maximized operation with following key functions:

• Operation planning and monitoring: Display required information of every BESS integrated in the system in remote control center by multi-screen, and let operators make the setting of schedule for constant power or load following for each BESS.
• Control and operations: Distributing the information to BESS for stable operations such as reference value for demand-power- level, reference-power (active/reactive) from the distribution management center and schedule warning alert.
• Battery monitoring: The charge-discharge rate, charge status and operation status of each battery are displayed.
 

Enabling Technologies

Renewable Power Plant Controller

Guarantee the delivery of a fixed amount of energy by leveraging intermittent resources and virtually eliminating energy waste. Stabilize the power supply by coordinating and dispatching generation and storage assets in real time to compensate for sudden load changes.
