“…Normally, heavy electrical loads and long distribution lines could be a problem for voltage control. Nowadays, the growing use of renewable energy sources [4] is modifying the behavior of the electrical system, especially in the distribution networks and consequently impacting the voltage profile in the area in which they are connected. For instance, distributed generation may cause overvoltage in moments of the day when the generation is maximum, and the load is low.…”

This paper proposes a new approach for evaluating distribution voltage regulators using quasi-static hardware-in-the-loop (HIL) simulation. Distribution voltage regulators are used to control the voltage using tap change transformers and are equipped with static control algorithms in order to accomplish different configurations of the distribution electric grid with typical load profiles. The growing penetration of renewable energy in electrical distribution systems is a great challenge for this equipment and it becomes paramount that its measurement and control algorithms adapt to this new reality. Hardware in loop testing (HIL) techniques could be used for assessing the performance of the voltage regulator equipment. Most applications of HIL are concerned with accessing the dynamics of electrical system including not only grid modelling, but also the real equipment involved and should be used to test the efficiency of voltage regulation. However, a more simplified approach concerning the HIL tool could be applied to testing distribution voltage regulators

“…It is pointed in [6] that since different services have different requirements, participating in multiple markets helps to better utilize the control flexibility of resources and obtain more benefits. To stack multiple services, energy storage systems are controlled in [7] to simultaneously participate in N-1 contingency requirement, voltage management and frequency regulation. An optimal control method is presented in [8] for energy storages to provide grid services including energy arbitrage, balancing service, capacity value and distribution system deferral, and outage mitigation.…”

This paper proposes a concept of generalized energy storage (GES) to facilitate the integration of large-scale heterogeneous flexible resources with electric/thermal energy storage capacity to participate in multiple markets. First, a generalized state variable referred to as degree of satisfaction (DoS) is defined, and dynamic models with a unified form are derived for different types of GESs. Second, a real-time market-based coordination framework is proposed to facilitate control, and ensure user privacy and device security. Demand curves of different GESs are then developed based on DoS to express their demand urgencies as well as flexibilities. Furthermore, a low-dimensional aggregate dynamic model of a GES cluster is derived thanks to the DoS-equality control feature provided by the design of demand curve. At last, an optimization model for a large-scale GESs to participate in both the energy market and regulation market is established based on the aggregate model. Simulations results demonstrate that the optimization algorithm could effectively reduce the total cost of an aggregator. Additionally, the proposed coordination method has high tracking accuracy and could well satisfy users' diversified power demand.

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] ...
