OPS provides power conversion and system control for advanced microgrid in UAE


The OPS Group is pleased to announce the successful commissioning of its latest renewable power project, situated at an off-grid industrial facility in the United Arab Emirates.

This project involved the integration of renewable energy and advanced batteries into the existing diesel power plant. The primary design objective of this system is to improve financial outcomes for the industrial facility, through a reduction in operating expenditures and lifecycle energy costs.

OPS integrated its advanced microgrid technologies, including parallel PIM power conditioners, MPPT chargers, and Prescient U10 microgrid controllers, with 300 kWp of solar generation, a 614 kWh lithium-ion energy storage system, and  two 500 kVA diesel generators. These gensets are now playing a backup role, with the facilities’ energy requirements predominantly supplied by renewable energy generation.

Microgrids exemplify the future of power in their application of advanced materials, software, and engineering. Due to the declining cost and improved performance of energy storage, microgrids are now capable of delivering utility grade power at lower lifecycle costs than competing options such as diesel, and without harmful environmental impacts. Recognised as a leader in microgrid controls, Optimal Power Solutions is proud to be at the forefront of this paradigm shift in power generation.

Results were published in August 2015 by Navigant Research, one of the key research programs with a focus on new technology and business models that are driving innovation in the clean energy sector and shaping the future of electrical grid networks.

Navigant considers OPS as one of the top three companies in the micro grid space, with our success underlined by a robust project portfolio, highly functional micro-grid controllers and our approach to optimisation of micro grids.

In the past twelve months, OPS have been busy developing a new range of high-capacity, parallel Power Inverter Modules, namely the OPS PRISM system, which provides even greater power stability for critical mission projects. These products have been deployed in various projects including energy-intensive, commercial facilities in Japan, now operating as “smart factories” and maritime defense operations at remote coastlines. We are currently undertaking system upgrades for pre-existing OPS systems to the new parallel power platform, enabling greater optimisation of renewable sources with advanced control features, resulting in reduced operational costs for our valued clients.

OPS is also continuing with R&D for the control and integration of newly-commercialised or prototype advanced battery technologies through collaboration with our technical partners and universities. This R&D allows OPS to develop state-of-the-art power control technology and products, in line with the latest energy storage device specifications, as well as develop control algorithms and strategies that enable the highest penetration of solar PV whilst optimising the total system. High penetration solar PV micro grids provide the greatest contribution of renewable energy sources and enable zero or very low diesel-fuel operation, resulting in best case levelised cost of electricity generation.

Australian coal prospects dim as PM Modi spotlights solar

India’s newly elected Prime Minister, Narendra Modi, has started his first term in office with a promise that the power-starved nation will strongly focus on solar power.

Narendra Taneja, head of energy in Modi’s Bharatiya Janata Party said “We look upon solar as having the potential to completely transform the way we look at the energy space,” said, as the BJT come to power last Friday (May 16) in the biggest electoral win in three decades.

Modi’s proposed “saffron revolution” is a political promise that holds a lot of appeal, as well as massive economic opportunity. Now, as Prime Minister, growing renewable energy generation will remain one of Modi’s top priorities, according to Taneja, especially solar, with its potential to create many jobs and supply millions of households not connected to the grid.

It is a heavy blow to the coal industry which presumed it was the only power source capable of delivering electricity, despite India’s notorious infrastructure problems. For coal exporting nations like Australia, however – who have been forging ahead with the development of new mega mines and infrastructure in the belief that coal is the only solution to India’s booming energy needs – this news will not be welcome.

And as recently as January, leading investment bank HSBC warned that the market value of the coal assets owned by Australia’s biggest mining groups could be slashed by nearly half – or more than $US20 billion – due to constraints of the global “carbon budget;” a concept HSBC says is gaining traction, given the climate science, and the implementation of pollution control policies in the US and China.

A month earlier, in December, the International Energy Agency trimmed its five-year forecast of global coal use, warning that environmental constraints, financing issues, and the current cost of coal exports raised “concerns about the economic feasibility of projects in the Galilee Basin.”

120 kW Smart Grid Factory Energy Optimisation in Japan

OPS is pleased to deliver a new PV rooftop project in Japan for  Kawasaki – Rikuso Co Ltd (located near Tokyo). The factory is a logistics control point and warehouse for manufactured items.

The PV Inverter battery system provides a continuous split phase  power supply to the main office in the factory during the daylight hours. At night load is controlled back to the  utility grid supply at 8pm and restated on renewables at 9am the next day. Under local regulations grid feed of the PV energy is not permitted.

The system is structured on 120 kW of PV array with different roof orientations. The energy storage is 480 kWh and Inverter is 60 kW.  The load is estimated at 20 to 50 kW. The Tokyo Electricity Commission charges a fixed rate of approx. 18 yen (about US$0.18) per unit plus a ‘basic charge’ of 1000 yen/month based on the peak kW recorded over a 12 month period.

This project will provide valuable information for further scale up in the Japanese smart grid market.
