Article
Heating, ventilation, and air conditioning (HVAC) systems are well proved to be capable to provide operating reserve for power systems. As a type of large-capacity and energy-efficient HVAC system (up to 100 MW), district cooling system (DCS) is emerging in modern cities and has huge potential to be regulated as a flexible load. However, strategica...
Article
Rapidly increasing distributed energy resources (DERs) bring more fluctuating output power to the distribution network and put forward a higher requirement on local regulation resources for maintaining the network's balance. Heating, ventilation, and air conditioning (HVAC) loads account for more than 40% of power consumption in modern cities and h...
Article
The residential air conditioners (RACs) are increasing rapidly in urban power systems and have been widely considered as good regulation resources for improving the system flexibility and resiliency. However, in practical power systems, it is difficult to comprehensively acquire millions of RACs’ operating data and buildings’ thermal data, which ma...
Article
Heating, ventilation, and air conditioning (HVAC) systems in buildings have great potential to provide regulation capacity that is leveraged to maintain the balance of supply and demand in the power system. In order to make full use of HVAC’s regulation capacity, it is important to accurately evaluate it ahead of time. Because physical model-based...
Article
District cooling system (DCS), a type of large-capacity air conditioning system that supplies cooling for multiple buildings, is an ideal resource to provide frequency regulation services for power systems. In order to provide high-quality services and maximize DCS’s revenue from the electricity market, an accurate estimation of DCS’s regulation ca...

... Since renewable energy does not generate emissions or contribute to climate change, it is an excellent alternative to fossil fuels. The adoption of renewable energy, by decreasing the usage of fossil fuels [5], assumes a crucial role in reducing the impact of climate change and ensuring a sustainable future for future generations [6]. For different types of renewable energy resources, the use of wind energy has proliferated in recent years, and many countries have started investing heavily in this form of energy production [7]. ...
... wind energy exhibits strong uncertainties due to the weather system's chaotic nature. The weather-dependent characteristic of wind energy and its strong variability and intermittence [8] could bring great challenges to the smart grid operation, including voltage and frequency instability [3,9]. The instability of wind energy could cause issues in the energy supply-demand balance, leading to a potential failure of the grid's control system [10]. ...
... However, the local accommodation of distributed RES generation is challenging, since the RES generation is intermittent, uncertain and often nondispatchable [3]. Microgrids, which provide interconnections among distributed RESs, dispatchable diesel generators and flexible loads, are regarded as a promising solution to promote the local accommodation of distributed RES generation [4]. ...
