“…In this paper, advantage of RESs was motivated. We extended our previous, Doostizadeh et al [15] presented an optimized algorithm, such that DERs can offer their reactive power capacity into HV transmission networks. To do so, a new procedure is introduced to calculate the deliverable DERs' reactive power from distribution networks to participate in the reactive power market on the high voltage (HV) transmission networks.…”

A B S T R A C TTraditionally, conventional generation units were used to provide ancillary services e.g. reactive power support, and spinning reserve. Nonetheless, with the emergence of highly penetrated distributed energy resources (DERs) systems and considering how beneficial they can be; it appears reasonable to use them as reactive power providers. Therefore, this paper introduces a new procedure for DERs to participate in the reactive power market. To do that, an algorithm is proposed to calculate the deliverable reactive power capability of DERs from distribution networks to transmission systems. Furthermore, a reactive power procurement model is introduced to consider DERs participation in the reactive power market. Finally, to show the effectiveness, and validity of this method many case studies are carried out on 33-bus distribution and CIGRE 32-bus transmission test systems

“…If bids are economic, wind generation would be shrunk to avoid over-generation [138]. New developments in the field of renewable energy resources have motivated a lot of studies of the capability of VERs in providing various ancillary services such as inertia response [139,140], frequency regulation [32,141], voltage support [142,143] and operating reserves [34,144,145]. However, high penetration of renewable energy resources might also raise the necessity of revisions in the current mechanism and design of ancillary services, and the hidden potential for the emergence of a unique market for energy, ancillary services and VERs as discussed in [35].…”

Power systems are evolving to the networks with proliferated penetration of renewable energy resources to leverage their environmental and economic advantages. However, due to the stochastic nature of renewables, the management of the rapidly increasing uncertainty and variability in power system planning and operation is of crucial significance. This paper represents a comprehensive overview of power system flexibility as an effective way to maintain the power balance at every moment. Definitions of power system flexibility from various aspects are explained to reach the reliable and economic planning and operation of the power system. The effects of the high penetration of variable energy resources on power systems and the evolution of flexibility in response to renewables are studied. A variety of resources during the flexibility evolutionary transition are introduced and discussed. As an influential flexibility solution in current power systems integrated with renewable resources, market design improvement is widely reviewed in this paper, and required modifications in market design mechanisms are investigated pertaining to various time horizons.

“…Specifically, ICT enables better provision of the aforementioned grid services, which are essential for the stable and reliable operation of the PS. The operation of these services, which are increasingly likely to be provided via digital markets (Doostizadeh et al 2018), have certain requirements on the ICT system. Failures in the ICT system may cause a degradation in the performance of the grid services, which in turn might affect the PS operation (Tøndel et al 2017;Rasmussen et al 2017).…”

The integration of ICT into power systems has increased the interdependencies between the two systems. The operation of power system depends on several ICT-enabled grid services which manifest the interdependencies. ENTSO-E system state classification is a tool that is widely used by operators to determine the current operational state of the power system. However, it does not adequately describe the impact of ICT disturbances on the operation of the power system. Despite their interconnections, the operational states of both systems have been described separately so far. This paper bridges the well-established ENTSO-E systems state classification with an ICT system state classification, forming a new model considering the state classification of the ICT-enabled grid services. The model is developed by first identifying the ICT-enabled services, remedial actions and the respective performance requirements that are required by the power system. Then the states of these services are specified based on the supporting ICT system. The resulting joint state description shows how performance degradation of ICT-enabled services (introduced by disturbances) can affect the operation of the interconnected power system. Two case studies of such ICT-enabled services, namely state estimation and on-load tap changer control, are investigated in terms of how their operational states affect the states of the power system. A third case study highlights the interdependencies that exist between the services. These case studies demonstrate the interdependencies that exist between power and ICT systems in modern cyber-physical energy systems, thus highlighting the usage of a unified system state description.
