National Projects

The objective of the project (PTDC/EEI-EEE/31711/2017) is to develop a methodology and operational tool for the analysis of dynamic line rating (DLR) in power grids in order to facilitate optimal and economical integration of renewable generation.

Dynamic line capability analysis is used to assess, in real time, the instantaneous capacity of overhead lines in electrical power systems. Although the benefits resulting from the application of DLR techniques vary with the site, due to their correlation with weather conditions, preliminary studies indicate a potential with current limit values ("ampacity") higher than 20% when compared with traditional values calculated based on conservative operating assumptions.

The OptiGRID project (and the tool to be developed) will demonstrate the benefits of using DLR techniques with regard to: 1) increased levels of renewable energy integration (avoided cut) into the electrical system Portuguese and 2) reduction in the number of hours in market separation in the Iberian Electricity Market (MIBEL) and consequent impact on the prices of this electricity market,  contributing to an energy-efficient economy.

In the OffshorePlan project (POSEUR-01-1001-FC-000007) methodologies were developed and applied to analyze the energy resource of wind and waves from the perspective of planning, hierarchization and phasing out the installation of these marine renewable energy use systems in Portugal. The socio-economic and technical impacts associated with the integration of the production of marine renewable sources in the national electricity grid and the impact of their integration into the electricity grid and their planning were evaluated, with the aim of promoting and enhancing the implementation of these systems on the Portuguese coast, ensuring the maintenance of the quality and safety parameters of operation of the Portuguese Electric System. There were three main objectives of the project: 1)To identify renewable energy resources on the Portuguese Coast, through the construction of the wind and wave potential atlas; 2) Study of the impact of energy production (var-RES) at sea in the national electrical system through the construction and simulation of marine energy development scenarios on the Portuguese coast (until 2035) and; 3) Technical, economic and social analysis of the use of Energy at Sea.

The objective of this project (PTDC/SEN-ENR/114178/2009 and FCOMP-01-0124-FEDER-016080) was to characterize and categorize the rapid power fluctuations of wind generation in order to facilitate the operation of energy systems with a high penetration of wind generation. Given that wind energy has a fluctuating nature and is difficult to predict, operators of the electro-producing system – whose function is to ensure that production units are in balance with the needs of consumers – fear the impacts of this renewable source on system regulation and its classic operating strategy, especially when the annual contribution of wind energy shows significant values. Thus, the biggest challenge to the integration of large percentages of wind energy in energy systems is the fluctuating nature of this source, and it is essential to characterize its fluctuations and the effects of the aggregation of a high number of turbines in wind farms.

As part of the project, LNEG developed systematic methodologies for forecasting wind production ramps for integration into alert systems for electricity system managers.

The REIVE project, funded by the Innovation Support Fund (FAI), has developed integrated solutions and strategies for the management and control of the electricity grid and pre-industrial prototypes of advanced interface devices for electric vehicles (VE) and microgeneration systems in order to enhance the integration of renewable energy and VE into the Portuguese electroproducer system,  without causing negative impacts on the operation of the system. In particular, WP2 and WP3 focused on the development of energy quality analysis tools (i)   and (ii) the level of harmonic distortion in BT distribution networks. LNEG contributes to the optimization of energy quality analysis and harmonic distortion tools and in the quantification of the impacts of microgeneration and VE integration in a concrete case of BT distribution network.

The ROADMAP project (PTDC/ENR/105403/2008) was intended to present a strategy for the development of a national cluster for offshore renewable energies in Portugal in order to maximise the added value of the products and services developed by the cluster and contribute to economic growth, in particular by exporting to the international renewable energy sector by 2030 and placing Portugal as one of the world's leading countries in certain sectors  offshore renewable energy by 2050.

The objectives of the TURBan project (Contracto ADI/DEMTEC PRIME Program, no. 70/0201) were the development of two prototypes of microturbines suitable for installation in an urban and built environment, a horizontal axis turbine and a vertical axis turbine. As part of this project, the turbines were designed, designed and designed: i) T.URBan H2.5, a horizontal shaft turbine with a rated power of 2.5 kW; (ii) and TURBan V2.0, a vertical shaft turbine with a rated power of 2 kW. In addition to the cenception and design of these turbines, this project was part of the coordination and planning of experimental tests and campaigns associated with the optimization of the operation of horizontal and vertical axis turbine prototypes under the TURBan project, as well as the evaluation of the performance of the prototypes.

The first prototype of this turbine was installed in the gardens of the palace of São Bento, at the request of the services of the prime minister's civil house under the presidency of the European Union by Portugal in 2007. After the completion of the project, a process of technology transfer of the prototype of the T.URBan H2.5 horizontal axis turbine was initiated for the company FREZITE, and project dossiers and characterization of the operation of its different components for the purpose of industrialization of the identified manufacturing processes were prepared. After studying the industrialization dossier (elapsed between 2010 and 2011) affected by the financial crisis, the company did not carry out the process of transferring know-how and industrialization of the prototype.
