Economic Advantages of Office Buildings Providing Ancillary Services with Intraday Participation

Colin Neil Jones, Ioannis Lymperopoulos, Faran Ahmed Qureshi, Ali Ahmadi Khatir

Controlling the consumption profile of office buildings can be used to provide balancing services to the power grid at a financial benefit without violating its thermal comfort constraints. The economic advantage of such a service is a reduction in the tot ...

Developing Offer Curves for an Electric Railway Company in Reserve Markets Based on Robust Energy and Reserve Scheduling

Sidi-Rachid Cherkaoui, Mokhtar Bozorg, Ali Ahmadi Khatir

This paper proposes an appropriate offering strategy method for an electric railway company (ERC) to participate in reserve markets. In this respect, first the problem of energy and reserve scheduling for the ERC is modeled in a deterministic way. Next, a ...

Providing ancillary service with commercial buildings: the Swiss perspective

Colin Neil Jones, Ioannis Lymperopoulos, Faran Ahmed Qureshi, Ali Ahmadi Khatir, Xuan Truong Nghiem

Ancillary services constitute the cornerstone of the power grid. They allow for an efficient system operation, provide resilience to uncertainties and establish safeguards against unprecedented events. Their importance is growing due to the rise of grid de ...

Multi-Area Energy and Reserve Dispatch Under Wind Uncertainty and Equipment Failures

Sidi-Rachid Cherkaoui, Ali Ahmadi Khatir, Antonio J. Conejo

The cross-border trading among electricity markets in an interconnected multi-area system (e.g., in central Europe) and the integration of renewable resources (e.g., wind energy) have remarkably increased in recent years. To efficiently operate such system ...

Reserve services management in multi-area power system under uncertainty

Ali Ahmadi Khatir

The reserve is a service traded in the market to counteract unpredictable changes in system conditions. The efficient market-clearing procedure relies on economic criteria while maintaining the system security by means of a proper reserve management progra ...

Probabilistic Spinning Reserve Provision Model in Multi-Control Zone Power System

Mokhtar Bozorg, Sidi-Rachid Cherkaoui, Ali Ahmadi Khatir

Inter-zonal trading in multi-area power system (MAPS) improves the market efficiency and the system reliability by sharing the resources (energy and reserve services) across zonal boundaries. Actually, each area can operate with less reserve resources than ...

Reactive power reserve management: Preventive countermeasure for improving voltage stability margin

Sidi-Rachid Cherkaoui, Mokhtar Bozorg, Omid Alizadeh Mousavi, Ali Ahmadi Khatir

Voltage stability imposes important limitations on the power systems operation. The system should be operated with an adequate voltage stability margin by the appropriate scheduling of reactive power resources and voltage profile. The main countermeasures ...

A probabilistic spinning reserve market model considering DisCos different value of lost loads

Sidi-Rachid Cherkaoui, Ali Ahmadi Khatir

In practice, some customers like industrial ones have higher value of involuntary lost load (VOLL) than other customers and thus, are willing to pay more for higher reliability levels than those with less VOLL, and consequently, they are more concerned wit ...
