Special Issue Information

Dear Colleagues,

The integration of renewable energy sources into modern power grids is a highly relevant topic, not only for academic research but also for all industrial stakeholders. The energy transition towards a carbon-free generation system makes this Special Issue critical, particularly from the perspective of power grid planning and infrastructure development.

Present power grids are usually not properly designed to handle great amounts of energy from many renewable sources. Unlike conventional generation systems, renewable energy sources are not as predictable but are driven by a high degree of variability. This adds complexity to the management of energy flows, which must be handled with advanced organization and novel control strategies to ensure the stability and reliability of the grid.

In this context, this Special Issue seeks to broaden the horizon surrounding the integration of renewable energy sources into the power grid. It aims to highlight the most recent methodologies and technological advancements that enable seamless integration, focusing not only on present solutions but also on the outlook for grid evolution while considering future development perspectives in light of recent national and international decarbonization plans.

The topics welcomed by the Special Issue include, but are not limited to, the following:

  • Technological innovations;
  • Challenges of intermittency and variability;
  • Role and development of energy storages;
  • Static and dynamic impact of the integration;
  • Advanced grid control systems;
  • Policy and regulatory frameworks;
  • Prosumer engagement;
  • New market dynamics;
  • Integration of electric vehicles;
  • Access to distributed data sources from power system stakeholders;
  • Long-term prospects for 100% renewable energy power systems.

This paper explores the integration of microgrids within utility networks and distinguishes selfish from collaborative microgrids. Research has shown that selfish microgrids tend to increase volatility of order updates to power generators, whereas collaborative microgrids decrease that volatility, resulting in smoother, more controllable operations of networks. This paper proposes an analytical formula linking power volatility to power quality, i.e., to issues such as voltage dips, surges, and transients. These are known risks for disrupting the operation of utility grids, causing instability and jeopardising efficiency and reliability. As collaborative microgrids reduce volatility, they improve power quality. That argument is extended to propose that collaborative microgrids can act as quality improvements agents within wider networks. Full article

Offshore wind (OSW) energy represents a vast and largely untapped resource capable of significantly contributing to the rising global electricity demand while advancing ambitious decarbonization and clean energy transition goals. Despite its potential, the effective harnessing of OSW is contingent upon the strategic and reliable integration of offshore generation into existing onshore AC power systems. Multi-terminal high-voltage direct current (MTDC) networks have emerged as a promising solution for this task, offering enhanced flexibility, scalability, and operational resilience. However, several technical and operational challenges—such as lack of standardization, coordinated control of multiple multi-vendor converters, reliable communication infrastructures, protection schemes, and seamless integration of offshore HVDC substations—must be addressed to fully realize the benefits of MTDC systems. This review paper critically examines these challenges and proposes a control, communication, protection, and HVDC substation design that could be adopted as an initial guideline for the efficient and secure integration of OSW into AC grids. By identifying current research gaps and synthesizing existing solutions, the paper provides a comprehensive framework for optimizing the role of MTDC networks in future offshore wind deployments.
