General objective and energy context
The general objective is to increase the competitiveness of research. We stimulate strategic partnerships in the vast energy field. The project brings together ICMET Craiova, universities and the industrial applicant INDAELTRAC. Together we create an extremely useful innovative product. It ensures the safety of electricity supply. We strictly comply with the quality indicators in current legislation.
The energy of the future aims at two major operating concepts. These are local networks and smart grids. The first concept makes excellent use of renewable and conventional energy resources. The second concept aims at creating a European energy system. It relies heavily on IT and control components.
Current challenges and proposed solution
The integration of renewable resources increases the number of power electronic equipment. These practically represent a large class of nonlinear loads. The dynamics of energy consumption strongly modify the power circulation. Thus, negative effects appear on the maintenance of essential electrical quantities. Existing quality standards become much more difficult to comply with. Therefore, we urgently need new specialized equipment. These must reduce the negative impact between networks and consumers. The ultimate goal is the visible improvement of the quality of electricity.
Functions of the new unified electronic conditioning equipment:
- Fluid bidirectional circulation of electricity;
- Ensuring a constant and sinusoidal voltage at the user's terminals;
- Compensation of non-active power consumption with unity power factor;
- Rapid integration into today's smart energy grid.
The innovative character and the experimental model
The experimental model pursues a dynamic compensation of the power factor. The equipment promptly eliminates the distortions of the current and voltage curves. The operation remains stable regardless of the type of electrical load connected. The research work has a strong innovative character. This is determined by the clear needs of the end consumers.
We propose an innovative electrical conditioning and control system. It is installed in the connection node of a microgrid. The system regulates the parameters disturbed by strongly nonlinear consumers. Model validation is assisted by modern specialized software applications. We use recognized programs such as EDSA Technical 2004 and PowerWorld.
The novelty of the project lies in the implementation of advanced technological concepts. We use the FACTS and FRIENDS principles in our technical development. These concepts are perfectly embodied in the final experimental model. This solution fully satisfies all the requirements of electricity consumers.
Development stages and results
Stage 1 (Completion deadline: 31.12.2014)
We have substantiated the necessary technical and constructive solutions. These aim at an adaptive electrical correction system. The system corrects parameters in low voltage networks. It is intended for microgrids with renewable energy sources. The equipment is perfectly integrable in modern SMART GRID networks.
Stage 2 (Completion deadline: 31.12.2015)
We continued to substantiate the technical and constructive solutions. The low voltage networks and the interconnection of renewable sources were targeted. We designed and developed all the technical documentation. Finally, we physically realized the experimental model of the equipment.
Stage 3 (Completion deadline: 31.12.2016)
In this phase we experimented with the functionality of the model we created. We practically demonstrated the usefulness of this equipment in the network. We developed the documentation for property rights. We carried out information and scientific dissemination actions. The publicity targeted the project and the excellent results obtained.
Stage 4 (Completion deadline: 30.09.2017)
The last phase included the final experimentation of the model. We have once again demonstrated the functionality at high standards. The dissemination of the results continued strongly in the specialized environment. The project ended with a very important step. We have developed a patent application.
