Development and initial testing of a virtual laboratory for the build up and testing of microgrid management algorithms




HIGHLIGHTS
  • What: The work presented in this paper provides additional capabilities such as the possibility to store the data exchanged between laboratories in time series and relational databases, the possibility to use REST API-based communications and dashboard and alerting applications. The aim of this module is to manage a charging point in a versatile and modular way, taking into account the possibility of supplying an ultrafast charge or multiple fast charges, alternatively, and the eventual integration of a distributed generation point (photovoltaic plant) serving the same charging station. This research has received funding from the European Union`s Horizon 2020 Framework Program for Research and Innovation under grant agreement no. 893857.
  • Who: n from the Centre for the Development of Information and Communication Technologies in Asturias: CTIC Centro have published the article: PREPARACION OF FUL PAPER FOR THE INTERNATIONAL CONFERENCE ON RENEWABLE ENERGIES AND POWER QUALITY, in the Journal: (JOURNAL)
  • How: To solve this issue this Article proposes the use of a laboratory digital twin i.e. a virtual laboratory with a behaviour that is similar to that of real installations aimed at facilitating the development testing and debugging of management algorithms. To mitigate these problems this paper proposes the creation and use of a virtual laboratory (see Fig 1). A series of experimental tests were conducted to demonstrate the capabilities of the virtual laboratory.
SUMMARY

    According to the International Renewable Energy Agency (IRENA), a microgrid can act as a platform, not only that facilitates the integration of variable Distributed Energy Resources (DERs) in a sustainable, price-competitive and reliable manner, but also as a resource that can provide key services to the main grid. Different technical partners are free to develop their own tools or modules and communicate and interact with each other, thanks to a “Communications Services Module”. A. Communications Services Module One of the main contributions of this system is that it implements a decentralized control approach, as each module is fairly autonomous and complex. The “Commercial Building Module”, the “Generic Prosumer Module” and the “High-Power EV Charger Microgrid Module” calculate the optimal economic operation for the next 24h in 15-minute steps. Local modules send working profiles (grid interaction profiles, the demand and/or generation added curves) to the “Microgrids Coordinator Module” through the “Communications Services Module”. “Microgrids Coordinator Module” asks through the “Communications Services Module” to the chosen prosumers for flexibility. Inquired prosumers send their flexibility possibilities to the “Microgrids Coordinator Module” through the “Communications Services Module”. The “Microgrids Coordinator Module” chooses the best technical and economical solution for the grid operation from among the communicated flexibility possibilities. The “Microgrids Coordinator Module” sends through the “Communications Services Module” operation set points. As starting point, the Optimization Module of the Generic Prosumer Module, described in section B.1, was used to generate the power generation and consumption baselines for all the technologies per end-user, considering the day ahead prices from OMIE (Operador del Mercado Ibérico de Energía in Spanish) and the time series of irradiance and temperature from a city in Spain for a sample day. @@

Exploring the bilayer approach to analyzing lead-free perovskite solar cells` numerical aspects for high efficiency

HIGHLIGHTS What: According to this paper a volume lead-free perovskite structure is quantitatively investigated using 1D solar cell capacitance simulator (SCAPS) software. Developing the proposed device structure in an experimental environment is the aim of this preliminary study. In this work, the amphoteric defect with uniform energy distribution above the absorber layer`s Ev was investigated. Who: Shahid Farhan et al. from the Department of Electrical Engineering, Government College University, Pakistan have published the research: Exploring the Bilayer Approach to Analyzing Lead-Free Perovskite Solar Cells` Numerical Aspects for High Efficiency, in the Journal: (JOURNAL) Future: The expected results of this research are expected to provide significant perspectives for the future research and manufacturing of lead-free PSCs with an emphasis on their commercial feasibility. SUMMARY Transport layer (ETL), a perovskite absorber layer, and a hole transport layer (HTL) a...

Can europe recover its photovoltaic manufacturing capacity?

HIGHLIGHTS What: Figure 2 below illustrates the changing dynamics of the global PV market, and the influence of the Chinese PV market, 2 For the purpose of this report, IEA PVPS countries are those that are either member in their own right or through the adhesion of the EC. but also the fast pace of growth in India and emerging countries. Who: Melodie de l`Epine from the Japan Japan have published the Article: Snapshot of Global PV Markets -, in the Journal: (JOURNAL) of 23/04/2023 Future: Repowering is still relatively unusual given the age of the oldest installations but it is expected to increase in the near future – serial defects with backsheets manufactured in the period 2009 – 2011 is a good example as the past 2 years have seen a few hundred MW replaced. As penetration rates increase new governance models compatible with market and climate policy driven deployment targets will need to be established to ensure PV can be smoothly deployed.
