Optimal Design for Photvoltaic Plants

25.06.2012
A newly developed software system improves and accelerates the planning process for photovoltaic facilities built in open spaces.

Such power plants have to be customized in line with the given terrain, weather conditions, customer requirements, and the types of solar modules to be used in them. PVplanet (PV Plant Engineering Toolbox) from Siemens generates hundreds of different plant layouts within a just a few seconds.



It can also analyze conflicting planning objectives such as electrical output and costs, and the effect they will have on one another. As a result, the software reduces planning times by around 80 percent as compared to the common process to date of creating individual layouts and comparing them. Siemens Energy has been testing an initial version of PVplanet since April 2012.

The share of electricity generated by photovoltaic power plants on roofs or in open spaces is increasing. Installed photovoltaic output tripled worldwide between 2009 and 2011 alone. The solar cells used in photovoltaic plants convert sunlight directly into electrical energy. Planning large facilities is a very complex process, however.

For example, if you spread the solar modules far apart, you can reduce the shadow each module will cast on the others, thereby increasing efficiency. This causes a problem, however, because increasing the distance between modules means fewer installed modules and thus less overall output. Planning engineers therefore have to make technical and economic compromises for a large number of parameters, while still meeting customer requirements regarding aspects such as minimum output or cost limits.

In order to make this planning easier, Siemens Energy and the Fraunhofer Institute for Industrial Mathematics (ITWM) have developed the PVplanet planning tool, which simultaneously calculates the cost and potential output of a large number of possible designs and then identifies the best solution. The software is based on mathematical algorithms specially developed by ITWM, as well as the wealth of experience Siemens has in designing solar power plants.

Engineers who use the software initially enter basic conditions such as topography and weather. After that, they select module and inverter types and can also alter or limit parameters like angles of inclination, service access ways, and component costs. The software uses the results to calculate the electricity production costs and thus the potential profitability of a given facility layout.

PVplanet will made available to the engineering teams at Siemens' regional units and be further refined this fall.

Im Focus: Neutron star merger directly observed for the first time

University of Maryland researchers contribute to historic detection of gravitational waves and light created by event

On August 17, 2017, at 12:41:04 UTC, scientists made the first direct observation of a merger between two neutron stars--the dense, collapsed cores that remain...

Im Focus: Breaking: the first light from two neutron stars merging

Seven new papers describe the first-ever detection of light from a gravitational wave source. The event, caused by two neutron stars colliding and merging together, was dubbed GW170817 because it sent ripples through space-time that reached Earth on 2017 August 17. Around the world, hundreds of excited astronomers mobilized quickly and were able to observe the event using numerous telescopes, providing a wealth of new data.

Previous detections of gravitational waves have all involved the merger of two black holes, a feat that won the 2017 Nobel Prize in Physics earlier this month....

Im Focus: Smart sensors for efficient processes

Material defects in end products can quickly result in failures in many areas of industry, and have a massive impact on the safe use of their products. This is why, in the field of quality assurance, intelligent, nondestructive sensor systems play a key role. They allow testing components and parts in a rapid and cost-efficient manner without destroying the actual product or changing its surface. Experts from the Fraunhofer IZFP in Saarbrücken will be presenting two exhibits at the Blechexpo in Stuttgart from 7–10 November 2017 that allow fast, reliable, and automated characterization of materials and detection of defects (Hall 5, Booth 5306).

When quality testing uses time-consuming destructive test methods, it can result in enormous costs due to damaging or destroying the products. And given that...

Im Focus: Cold molecules on collision course

Using a new cooling technique MPQ scientists succeed at observing collisions in a dense beam of cold and slow dipolar molecules.

How do chemical reactions proceed at extremely low temperatures? The answer requires the investigation of molecular samples that are cold, dense, and slow at...

Im Focus: Shrinking the proton again!

Scientists from the Max Planck Institute of Quantum Optics, using high precision laser spectroscopy of atomic hydrogen, confirm the surprisingly small value of the proton radius determined from muonic hydrogen.

It was one of the breakthroughs of the year 2010: Laser spectroscopy of muonic hydrogen resulted in a value for the proton charge radius that was significantly...
