Special Issue Information

Dear Colleagues,

Due to environmental and sustainability concerns, power systems worldwide are in the middle of a rapid transition. Large conventional generators are being phased out and replaced with mainly converter-interfaced renewable energy sources (RESs) such as wind power and solar photovoltaic.

The dominance of converter-based generation in modern power systems poses new stability issues and requirements for the controls due to the different physical characteristics and interaction with the grid of converter-interfaced components. A way to integrate RESs into power systems is through the concept of smart grid technology. However, safely and securely integrating large shares of variable RESs is still a challenge for most power systems. There is a need to replace the ancillary services provided by conventional generators, such as inertial, primary, and secondary voltage and frequency control. On the other hand, current electricity markets were designed on concepts developed for a generation fleet that was predominantly conventional fossil fuel. Therefore, there is a need for redesigning these markets and successfully integrating high levels of RESs.

This Special Issue focuses on the latest developments in renewable energies and smart technologies. In particular, the Special Issue targets applied research from both academia and industry on the following topics:

  • Conventional and innovative inertia-based RESs, e.g., hydropower, tidal
  • Inverter-based RESs, e.g., wind and solar
  • Impact of RESs on power system dynamics
  • Frequency regulation and control under high penetration of RESs
  • Security of supply and generation adequacy in renewable-based systems
  • Integrating RESs into existing and new electricity markets
  • Decision-making under uncertainty in electricity markets
  • Integration of distributed energy resources
  • Control and management of RESs
  • Network digitalization and smart metering infrastructures
  • Distribution grid observability, automation, and supply quality
  • Protection schemes, islanding, and microgrids operation
  • Decentralized and distributed control solutions for energy systems
  • Flexibility services and demand response programs
  • Black start capability and emergency power reserves
  • Grid modeling and simulations
  • Energy storage and applications
  • Grid forming and following converter control
  • Ancillary services from inverter-based generators, i.e., voltage and frequency control, fast fault current injection

Water is the basis of life for living creatures and is used for various purposes, especially in agriculture, industry, municipal services, and energy production. Assessing water quality in terms of its various uses is not without significance. This study investigates the water quality within two small hydropower plants (SHPs) in central European urban areas from an environmental perspective. Wrocław I and Wrocław II SHPs on the Odra River in Poland were selected as case studies. This study presents the results of four-year observations (2017–2020) conducted in different locations located upstream and downstream of the barriers. The following aspects were assessed: physicochemical status, trophic status, assessment of fish living conditions, and water quality indices. The results show that SHPs improved the average physicochemical status of the five-day biochemical oxygen demand (i.e., BOD5; by 6.19% comparing the results downstream and upstream of the SHPs), dissolved oxygen (3.85%), PO4-P (3.31%), and electrical conductivity (0.52%); however, they worsened in the case of the pH (by 2.63%) and NO3-N (by 1.83%). Water near the study cases is classified as mesotrophic or eutrophic. The conditions for salmonids and cyprinids were not met due to the increased concentrations of NO2 and BOD5 values; in the case of salmonids, also due to the temperature and dissolved oxygen concentration. The water quality indices differed and indicated the quality from poor to good, depending on the classification. This study provides important insights for policymakers regarding the awareness of the impacts of SHPs on water quality in urban areas and the immediate measure needed to be considered to improve aquatic habitat conditions.
