“…The results showed a high variance of energy production for systems with a high share of wind energy. In a context-related study, Chirapongsananurak and Santoso [23] created a tool for the simulation of power distribution circuits incorporating generation technology models and electromechanical models, such as transformers and capacitors. Huber et al [24] inspected grid load ramps in the context of renewable power generation systems.…”

The expansion of renewable energies and the concomitant compensatory measures, such as the expansion of the electricity grid, the installation of energy storage facilities, or the flexibilization of demand, lead to a more elaborated energy supply system. Furthermore, the technological development of small power plants has further progressed, and many novel technologies have achieved grid parity. For manufacturing companies, the integration of renewable generation plants at their own site therefore represents a promising strategy for being both technically independent of the electricity grid and autonomous of price policy decisions and volatile market prices. This paper outlines the existing decentralized, renewable power generation technologies, their energetic modeling, and a hybrid optimization methodology for their dimensioning that uses mixed integer linear programming (MILP) and linear programming (LP) problem formulation. Finally, the introduced dimensioning method is applied to an exemplary manufacturing company that is assumed to be in the central part of Germany and located in the metalworking sector. The company has an electricity demand of approximately 20,000 MWh/a. The optimization results in a maximum expansion of PV and the use of CHP to cover the base load leading to a promising energy cost reduction of almost 20%.

This paper presents a multiple time-step solver based on a time-domain explicit integration algorithm for improving the computational speed of high-voltage transmission line electromagnetic transient (EMT) simulation. For weakly rigid EMT models of high-voltage transmission lines, the previous precise Runge-Kutta integration method with a small time step is adopted; for strongly rigid nonlinear EMT models of high-voltage transmission lines, a an improved precise integration method using a large time step is used for the solver of EMT simulation. Practical simulations for overvoltages of high-voltage transmission line show that multiple time-step EMT solver can be applied to different cases of EMT simulation for transmission line.

Increasing the penetration of renewable energy sources such as photovoltaics, wind turbines, and tidal lagoon power plants raises concerns regarding their impacts on the power systems. Although wind and solar power generation can reduce the peak load demand in distribution circuits, these renewable energy sources may cause voltage and protection issues including voltage regulation, flicker, short-circuit current contribution, and protection coordination. Additional equipment such as capacitor banks, voltage regulators, static var compensators (SVCs), static synchronous compensators (STATCOMs), and energy storage systems may be required to provide enhanced voltage regulation.The Special Issue "Inventions and Innovation in Integration of Renewable Energy Systems" has provided an insight into the different aspects of renewable energy integration. There are six papers published in this special issue as follows:The first paper [1] presents a framework for deploying energy storage (ES) systems to simultaneously provide stacked benefits for the distribution system. In this paper, ES is used to provide the N-1 contingency requirement as a primary application. During normal operating conditions, ES is used for multiple secondary applications, including voltage management and frequency regulation. The framework proposed in this paper is generic and can be easily adapted for other feeders, with a different set of primary and secondary application scenarios.The second paper [2] develops an integrated multi-time-scale simulation tool for analyzing the renewable energy integration in distribution circuits. The proposed tool includes three circuit equipment models for the simulations in three different time scales, which are steady-state, electromechanical transient, and electromagnetic transient models. The proposed tool can switch from one single-time-scale model to another single-time-scale model when the power system phenomena with different time scales occur. Therefore, this tool is useful for performing a long-term simulation involving the power system phenomena spreading across time scales.The third paper [3] proposes a technique to visualize the results obtained from the quasi-static time-series simulations of large distribution circuits. The proposed technique uses the probability density evolution to visualize the distribution of electrical variables, such as, voltages along distribution feeders and show the evolution of circuit variables over time. One of the applications of the proposed technique is to help visualize the behavior of new devices in the power systems.The fourth paper [4] describes the historical developments of tidal energy and presents the recent advances in tidal lagoon technology. The mechanism of tide generation and the principles of tidal lagoon operation are presented. In addition, the paper also provides the characteristics of tidal power generation and discusses the opportunities, challenges, and solutions for integrating tidal lagoon power plants into the UK power system. The fifth paper [5] ...
