OPS Australia has recently upgraded the Parachilna solar hybrid diesel power station in South Australia.

The existing hybrid system was installed and commissioned in August 2002. This system has operated well to date however over the last year some operational issues had become apparent. One of the fundamental issues found was the lack of available technical support for the existing control system as well as the limited capability of outdated control system software. OPS was contracted to upgrade this system and has since integrated our digital signal processor (DSP) power control technology. OPS engineers were dispatched to site and completed this system upgrade within two days.

The new control technology provides the Parachilna client with high-speed remote control and monitoring software (SCADA) which provides further flexibility in the operation and maintenance of this solar diesel hybrid station. OPS Australia looks forward to future work within the Australian renewable marketplace and will continue to expand its operations, particularly in regard to solar diesel hybrid projects.

On February 07th 2011, Optimal Power Solutions engineers commissioned a new 360 kWp solar hybrid system at remote grid network located on Bunaken Island, North Sulawesi, Indonesia.

OPS supplied the power conversion and system integration technology, including a Hybrid Power Conditioner of 200 kVA rating, 2 x units of 180 kW Maximum Power Point Trackers (MPPT). OPS also supplied the power plant integration equipment including the AC Switching cabinet to accommodate the existing 2 x diesel engine generators rated at approximately 300 kVA each.

In the words of OPS engineer Zeke Paolinelli: “The first obstacle of this project was considering the status of the gensets. Due to old age and lack of remote control, the upgrade and design from OPS had to enable semi-manual genset operation. Many conditions have to be taken into account when manual operation of the genset is required by the operators. Because the OPS system is designed to work with little intervention from operators, instructions on how to operate the gensets under different situations was given through on-site training. More analysis with site data in the coming weeks will also enable OPS to improve the genset running hours as well as monitor the system under semi-manual mode and instruct the operators if required.”

The principal client for the Bunaken Job is the National Indonesian utility PLN, and the system was inaugurated by the Governor of North Sulawesi. OPS worked closely with a leading solar & building construction company in Indonesia market and looks forward to future collaborative projects.

Director of PT PLN Persero Mr Vickner Sinaga announced  that the new solar system at Bunaken is the first island in Indonesia to receive 24 hour power from an integrated solar hybrid system. The hybrid system is expected to displace diesel fuel with major positive effects for PLN, the consumers and the delicate island eco-system. The system is expected to meet the energy demands of the 680 Bunaken citizens and will provide for peak demands of 160 kW. Mr Sinaga also projected that the renewable component of this system will displace 260 kilolitres of diesel fuel per year at a saving of Indonesian Rupee 1.8 billion.

“The system was delivered with the presence of the Governor and other important people from Indonesian Government and PLN Utility. A large celebration followed as this was a very important occasion. Previously, the islands power demands were met at selected times, from diesel gensets only. Now, the gensets run one at a time, during 5 pm to 11 pm. The rest of the time, the batteries and solar PV provide power to the village. People from the village were extremely happy to finally have 24 hours of uninterrupted power supply, and also to have the diesel genset running for only a few hours a day instead of all day long,” (Zeke. P).

In June 2010 the City of Puerto Princesa in Palawan, Philippines formed a technical partnership with Optimal Power Solutions in order to address the city’s power shortage, currently estimated at 5 to 10 MW.

An ongoing and significant issue has been the provision of sustainable energy for Puerto Princesa. At present, diesel-powered gensets provide a capacity of 30 MW of power to the inhabitants of Puerto Princesa. OPS and the City Council plan to design and implement renewable energy sources to generate additional power supply, reduce diesel fuel consumption and promote a viable and sustainable energy future. It is envisaged that new renewable sources of up to 10 MW capacity will be integrated over successive phases. This renewable capacity will prioritise the export of photovoltaic power into the grid to better support and lower use of the current diesel generators. Phase One of 1 MW capacity shall be installed in 2011 progressing up to 2MW, 5MW and finally 10 MW providing for future load growth of the City.

The systems will combine solar photovoltaics, OPS proprietary inverter control technology, battery storage and diesel engines configured for 24-hour continuous power supply. OPS will provide the technical design, product technology, delivery, installation and service and maintenance of these new renewable services. The inverter technology will employ specially developed SCADA software for real time control management of the photovoltaic/diesel systems. This proprietary SCADA is currently in use in multi-megawatt grid-connect projects in India and has proven highly invaluable for real-time, remote monitoring of power generation and general system trends.

Puerto Princesa, Palawan: Background Context

Palawan is an island province of the Philippines located in the MIMAROPA region. Its capital is Puerto Princesa City and it is the largest province in the country in terms of total area of jurisdiction. Palawan is widely considered as one of the most important areas of biodiversity and conservation in the Philippines due to the outstanding environmental landmarks including spectacular limestone cliff formations, immense reefs teaming with marine life and significant mangroves. Puerto Princesa also contains an environmentally significant tidal underground river. Positioned in the Puerto Princesa Subterranean River National Park (PPSRNP), this unique natural phenomena was listed as a UNESCO Natural World Heritage Site in 1999. The PPSRNP is considered one of few examples in the Philippines whereby a concerted effort has been made to protect and manage the natural area.

The Puerto Princesa City Council is considered to be a leader of sustainable policies and is widely acknowledged as the cleanest and greenest amongst local Philippine governments. As a result, the PPSRPN and surrounding areas of Puerto Princesa are a source of national pride and a key element in the identity of the Philippine people. OPS looks forward to the ongoing technical involvement in regard to the development of sustainable energy and technology trends in the greater region of Puerto Princesa, Palawan.

Optimal Power Solutions has commissioned a unique hybrid power project in the Caribbean islands as of late April 2010.

Renewable energy is well positioned to address increasing energy supply concerns in the Caribbeans. Environmental concerns regarding diesel and fossil-fuel transportation have come to the forefront of political debate as the oil spill in the Gulf of Mexico continues to cause catastrophic damage. Furthermore, the landed cost of diesel is highly vulnerable to future price spikes and diesel is therefore a risky financial choice as the primary source of energy supply for off-grid requirements. Fortunately, the Caribbeans offer immense potential for new, off-grid renewable projects due to the plentiful solar and wind resource availability.

OPS is pleased to have provided the system integration for this hybrid renewable system that includes solar photovoltaics, wind turbines, diesel generators and proprietary OPS power conversion technology.

This project compromises 2 x 300 kW Hybrid Power Conditioning (HPC) inverters. Our HPC product provides a complete tecnological solution for off-grid renewable energy systems. This unit can operate in parallel with the generators to meet peak loads and features a flexible operating platform for integrating other balance of system components, in this case, the solar PV, wind-turbines and battery storage.

Renewable components of this system include 8 x 15 kW wind turbines and approximately 240 kWp of solar PV that utilise two large capacity OPS Maximum Power Point Tracker’s. In addition, the system utilizes 3 x 312 kVA diesel gensets and a 360 v battery bank rated at 6000 Ah, capable of providing 2.16 MWh of energy storage. The AC system sources are switched through a customised AC switching cabinet that is rated at 1.5 MW. In addition, OPS supplied a Station Control Module that incorporates local and remote access to the system.
