“…In this section we consider the availability of lithium batteries for the consumers. Batteries may help consumers in smoothing their consumption from peak time to other hours of the day (Schroeder (2011) and Díaz-González et al (2012)), leading to an electricity system where increasingly the "demand follows generation". We investigate how storage and interconnection between Ireland and France affect the welfare changes in these two countries and how these investments interact.…”

A longstanding goal of the European Union (EU) is to promote efficient trading between price zones via electricity interconnection to achieve a single electricity market between the EU countries. This paper uses a power system model (PLEXOS-EU) to simulate one vision of the 2030 EU electricity market based on European Commission studies to determine the effects of a new interconnector between France and the Single Electricity Market of Ireland and Northern Ireland (SEM). We use the same tool to understand the effects of investment in storage, and the effects of the interaction between storage and additional interconnection. Our results show that both investments in interconnection and storage reduce wholesale electricity prices in France and Ireland as well as reduce net revenues of thermal generators in most scenarios in both countries. However, France is only marginally affected by the new interconnector. Renewable generators see a modest increase in net revenues. The project has the potential for a positive impact on welfare in Ireland if costs are shared between countries and remain below 45 million €/year for the scenarios examined. The owners of the new interconnector between France and SEM see increased net revenues in the scenarios without storage. When storage is included in the system, the new interconnector becomes less profitable.

As a result of the increasing integration of renewable energy sources, power system is changing to a low inertia system with intermittent power supply. Frequency stability is therefore difficult to be maintained. Rather than increasing the spinning reserve capacity from conventional fossilfuel generators, the use of Energy Storage System (ESS) for frequency response is considered as a technically viable lowcarbon solution. To facilitate the grid-level study which aggregates a number of widespread small-size ESS, simplified models of multi-type ESSs including batteries and flywheels were developed. A generalized frequency controller was developed and applied to the aforementioned types of ESS. The controller coordinates the response amongst a population of ESS based on the units' State of Charge indicator. An adaptive droop control is combined with the coordinated control to guarantee a linear frequency response provided by a smaller number of ESS units. The number of charging and discharging of each unit is therefore reduced which prolongs the lifetime of the ESS units. Case studies were carried out by connecting a number of multi-type ESSs to a simplified GB power system model. Results show that the grid-scale ESSs are able to provide frequency response similar to but faster than frequency-sensitive generators. Implementation of ESS is therefore technically feasible to support the grid frequency stability with the reduction in the spinning reserve capacity.

“…Moreover, they can also take up the role of spinning reserve and provide energy for a black start, load leveling, ride through support, and unbalanced load compensation. The application of FESS in power systems is commonly investigated in association with grid-connected wind farms [4]- [8] for smoothing power oscillations generated by wind oscillation, or in a low-inertia microgrid [9]- [11]. FESSs have also been used for voltage sag mitigation in a shipboard power system [12].…”

Real-time simulation of power system transients inevitably demands computation time steps of the order of microseconds or even less. This enables Power-Hardware-inthe-Loop (PHIL) testing of new power system components, such as innovative energy storage systems, which is an efficient costeffective method to analyze the behavior of the component, prior to the grid connection. Having accurate real-time simulation models of the components is an essential step, prior to the PHIL testing. The new-generation Flywheel Energy Storage System (FESS), which uses High-Temperature Superconductors (HTS) for magnetic levitation and stabilization, is a novel energy storage technology. Due to quick response times, high power densities and high number of charging/discharging cycles, this new-generation FESS is especially suitable for enhancing power quality and transient stability in power systems. In this paper, the modeling and implementation of a FESS with HTS bearings in a real-time simulation environment are presented. The obtained real-time simulation results confirm the effectiveness of using such a FESS for improving power quality, e.g. voltage sag compensation in distribution networks and supporting the grid during frequency disturbances.
