Special Issue Information

Dear Colleagues,

When looking at the roadmap to achieve the 2050 European energy and climate sustainability goals for renewable energy, the most recent trends of CO2 emissions and energy efficiency indicate that R&D efforts must combine electricity and heat at the global and local levels.

For this purpose, a multi-energy approach to energy generation and conversion is required to release the full potential of intermittent renewable energies.

In this context, certainly electrical and thermal energy storage plays a key role, as it allows not only to manage properly the mismatch between the daily and seasonal demand and the local thermal and electrical generation (mainly based on solar energy) profiles but also to enhance the limited programmability of the generation and variability of thermal and electrical load demands. Therefore, hybrid storage (i.e., storage of electricity and heat) is indispensable for creating flexibility, allowing to optimize the balance between supply and consumption profiles at the lowest cost.

The complexity and multidisciplinary characteristics of hybrid storage systems require research efforts to propose synergy and multidisciplinary investigations linking industrial engineering, material science, building physics, electrical engineering (e.g., smart grids).

Storage technologies (electrochemical, thermal, mechanical, etc.) have heterogeneous features and performances; therefore, it is essential to explore different technologies in order to develop a wide range of alternatives, for which a techno-economical assessment is also available.

The main goal of this Special Issue is to report an updated view of the research status about the integration, optimization, and operation of building energy systems that include hybrid storage technologies, optimize supply, storage, and demand of electricity and heat, and increase the self-consumption of local renewable energy.

The topics of interest in this Special Issue on hybrid energy storage systems (HESS) include (but are not restricted to):

  • HESS applications in stationary systems
  • HESS in microgrids
  • HESS in photovoltaic/thermal (PVT) systems
  • HESS structure/topology
  • HESS control
  • HESS modelling
  • HESS design based on field data
  • HESS efficiency improvement
  • HESS optimal sizing and optimal management
  • Short-term and long-term economic assessment of HESS
  • Life span assessment of HESS components

Traditional hierarchical control of the microgrid does not consider the energy storage status of a distributed hybrid energy storage system. This leads to the inconsistency of the remaining capacity of the energy storage system in the process of system operation, which is not conducive to the safe and stable operation of the system. In this paper, an improved hierarchical control strategy is proposed: the first allocation layer completes the allocation between the distribution energy storage systems considering the state of hybrid energy storage systems, and the second allocation layer realizes the allocation within the hybrid energy storage systems based on variable time constant low-pass filtering. Considering the extreme conditions of energy storage systems, the transfer current is introduced in the second allocation process. The SOC (stage of charge) of the supercapacitor is between 40% and 60%, which ensures that the supercapacitor has enough margin to respond to the power demand. An example of a 300 MW photovoltaic microgrid system in a certain area is analyzed. Compared with the traditional hierarchical control, the proposed control strategy can reduce the SOC change of a hybrid energy storage system by 9% under the same conditions, and make the supercapacitor active after power stabilization, which is helpful to the stable operation of the microgrid.
