Special Issue Information

Dear Colleagues,

The reliability and sustainability of modern power systems are critical, especially for infrastructure power systems. For example, a power grid is defined as strategic infrastructure where faults and an unsustainable power supply may have a negative economic, functional, and defensive impact on the whole country or its areas.

The reliability and sustainability of power systems can be affected by several aspects. The first is the constantly increasing integration of renewable energy sources and distributed generation, increasing the risk of short circuits and over-voltages. These faults can cause significant damage to the power system. Therefore, it is important to develop modern protection methods and devices. The second aspect is cyber security. Cyber-attacks can cause confusion in the power grid’s information systems as well as blackouts.

The aim of this Special Issue is to bring together original, theoretical, and practical ideas, in the hope of developing future trends in the fields of power system reliability and sustainability. Topics of interest include, but are not limited to:

  • New approaches for reliable power system planning and operation.
  • Renewable energy resources integration.
  • Reliability evaluation in electric vehicles, power stations/substations, and energy storage systems.
  • New energy storage technologies in power systems.
  • Reliable BMS operation.
  • Reliable converter.
  • Fault current limiters—topologies and control methods.
  • Digital protection methods.
  • Circuit breakers.
  • Relays.
  • Phasor measurement units.
  • Protection challenges under renewable energy penetration.
  • Cyber protection.
  • Implementation of artificial intelligence for reliability improvement.

The power consumption analysis of a university campus can provide a unique opportunity to gain insight into the patterns and trends of multipurpose commercial buildings. The result of such an analysis may lead to the exploration of methods to integrate local and cleaner power generation. In this paper, we discuss the consumption patterns of the campus buildings of the Wentworth Institute of Technology for one calendar year. We analyzed the campus’s power consumption, comparing weekdays vs. weekends, academic vs. residential. The aggregate consumption of all buildings and examples of individual building consumption data were also included. This study was conducted on a campus that has unique characteristics such as being in an urban area, having a New England climate, and being composed of a mixture of old and new buildings. The findings could provide insightful information to other universities and commercial campuses in moving toward energy consumption improvement and efficiency. Full article

Compensation Admittance Load Flow (CALF) is a power flow analysis method that was developed to enhance the sustainability of the power grid. This method has been widely used in power system planning and operation, as it provides an accurate representation of the power system and its behavior under different operating conditions. By providing a more accurate representation of the power system, it can help identify potential problems and improve the overall performance of the grid. This paper proposes a new approach to the load flow (LF) problem by introducing a linear and iterative method of solving LF equations. The aim is to obtain fast results for calculating nodal voltages while maintaining high accuracy. The proposed CALF method is fast and accurate and is suitable for the iterative calculations required by large energy utilities to solve the problem of quantifying the maximum grid acceptance capacity of new energy from renewable sources and new loads, known as hosting capacity (HC) and load capacity (LC), respectively. Speed and accuracy are achieved through a properly designed linearization of the optimization problem, which introduces the concept of compensation admittance at the node. The proposed method was validated by comparing the results obtained with those coming from state-of-the-art methods. Full article
