Special Issue Information

Dear Colleagues,

Renewable energy is an important part of the electricity system of countries worldwide, with a high market share corresponding to wind and solar energy. Their proportion accounts for over 50% or even 100% of the generating capacity in some European countries. In addition to addressing the problem of increasing electricity demand, wind and solar energy reduce CO2 emissions by eliminating the need to use challenging chemical energy sources. However, a persistent downside is the poor stability during operation. This presents many risks because of factors that lead to reduced power output, which generates uncertainty. Therefore, strategies for the optimal operation and control of solar–wind hybrid systems need to be researched toward improving the stability of power systems and coping with disturbances to these generation sources.

Many aspects related to the development of integrated solar–wind power systems can be investigated. First, it is necessary to consider the impact of these energy sources when integrated into the power system, depending on the installation area, to propose reasonable development orientations. Second, forecasting is a crucial element in the application and use of wind and solar energy. Forecasting results characterized by low error contribute to easy control of the system when errors occur. Third, power electronic converters are an indispensable component of renewable energy sources. Developing high-performance converters with advanced control algorithms can minimize power loss and ensure stable output responses. Finally, proposing a transaction strategy between power systems and microgrids or multiple microgrids can improve reliability and optimize electricity generation costs.

For this Research Topic, we would like to encourage original contributions regarding recent developments in suitable technologies, ideas, and solutions for solar–wind hybrid systems, for example:

  • Evaluating the impact of solar and wind generators penetrating power systems and solutions to improve operational stability.
  • Advanced control of power converters of a hybrid renewable energy source to minimize adverse impacts on the power system.
  • Different types of energy source combinations, modeling, power converter architectures, sizing, and optimization techniques used in hybrid renewable energy sources.
  • Optimization of energy transaction strategies and energy management systems for microgrids to increase system reliability and reduce operation costs.
  • Ancillary services, storage system solutions, and technology to support renewable energy.

Grid frequency must be regulated in its nominal range to guarantee the stable operation of an electric power grid. Excessive grid frequency excursions result in load shedding, grid frequency instability, or even synchronous generator damage. With the growing wind penetration, there is an increasing issue about the reduction in inertia response. This paper addresses a self-adaptive inertial control strategy for improving the frequency nadir and smoothly regaining the rotor speed to the initial working condition without causing a second frequency drop (SFD). The first objective is achieved by determining the incremental power considering the maximum rate of change of frequency; the secondary goal is realized by smoothly decreasing the power reference based on the decreasing function. Simulation results verify that the proposed control strategy not only boosts the frequency nadir but also guarantees the smooth rotor speed recovery with a negligible SFD. Full article
