Research and Development Project

The project is supported by the Bundesministerium für Bildung und Forschung.
(FÖRDERKENNZEICHEN: KF 3006101CL2)

safe zero-e

In cooperation with the department of informatics of the University of Bielefeld and Aerowest GmbH we are working on the project SAFE zero-e. Therefore we focus on the development of automatic solar potential analysis of facades on the basis of high defined aerial views for Bielefeld-Sennestadt. The target of the project is to investigate not used solar potentials in the area and to develop zero emission houses out of that building stock.

Research and Development Project

Funded by the Federal Ministry for Education and Research (grant number: KF 3006101CL2).

Small wind turbine analysis tool

Small wind turbine analysis tool: Analysis Tool for creating potential registers for small wind turbines on buildings. Funded by the Federal Ministry for Education and Research (grant number: KF 3006101CL2).

In cooperation with the University of Applied Sciences Berlin (HTW-Berlin), tetraeder.solar gmbh developed a tool that allows a potential assessment for the usage of wind energy on buildings by small wind turbines. On the basis of a 3D terrain model, wind speed data and with consideration of the existing law requirements, the suitability for the usage of small wind turbines on buildings were determined.

The project is financially supported with funds from the federal Ministry for Economy and Technology (support code EP100391)

SELN: Solar Energy – Local Networks

Public network operators have to ingest the whole energy feed generated by plants running under the Renewable Energy Law, preferential to energy from other sources and irrespective of the actual demand (access and acceptance obligation). Operators are obligated to upgrade their network in order to be able to ingest the prioritized energy, as long as the required measures are economically justifiable. By German law operators become liable to indemnify, if they neglect this obligation. (§ 19 Abs. 1 EEG) At the same time the portion of energy generated from renewable sources is constantly growing. The federal government’s original ambition, increasing the percentage to 12.5 %, has been outranged by far. In 2008 it was at 14.8 % already. The basic conditions for mains power supply change accordingly as they have to accept more and more energy generated from peripheral small energy plants. Up to now predicting their productivity and integrating it into power system planning is very difficult. On one hand because the prospective power generation is difficult to estimate, on the other hand because it is impossible to determine which station is going to be launched at what time.

Intention

The aim is to develop an automated analysis tool. The tool is able to predict the energy feed of each roof as accurate as possible and to estimate the possibility of an actual installation of a photovoltaic plant, based on spatial planning models. It gives municipalities a reliable basis for planning local climate protection and energy concepts. Operators of local networks are enabled to detect low capacities in advance and include them into their maintenance and upgrade concepts in accordance to the respective scenario and probability.

Benefits

A few exemplary scenarios for municipalities, local network operators, and real estate owners:

Simulating and Assessing an Initiative to Stimulate PV-Plant Installations

Municipalities come up with a concept for local climate protection and energy supplies. Simulation measures need to be evaluated, rough estimates on upcoming installations of private PV-plants are required.

Using Existing Transmission Capacities

A network operator analyses the exploitation of the existing mains supply. Wherever he finds free transmission capacities he compares them to roof areas that qualify for generating solar energy. To achieve better utilization he supports PV-system providers and real estate owners to invest in PV-plants in convenient locations – a win-win solution.

Visualizing Producer Density for Network Planning

A network operator is informed about upcoming civil engineering in his area. He is able to proactively check his network’s infrastructure in order to find out if upgrades are needed it in the construction area to ingest future energy feed. If upgrades are required he can take advantage of the construction work to cut his own costs.

The research and development project “SELN” is expected to deliver valid statements on the energy feed generated from PV-plants and make them available for planning and maintenance.
