Heating, ventilation, and air-conditioning (HVAC) systems are ideal demand-side flexible resources to provide regulation services. However, finding the best hourly regulation capacity offers for HVAC systems in a power market ahead of time is challenging because they are affected by non-Gaussian uncertainties from regulation signals. Moreover, sinc...

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...

With the increasing penetration of renewable generation integrated into power networks, how to manage uncertainties in optimal power flow (OPF) has become a major concern for network operators. This paper proposes a joint chance-constrained OPF model to tackle uncertainties. This model jointly guarantees the satisfaction probability of all critical...

Thermostatically controlled load (TCL, such as heating, ventilation, and air conditioning system) is a desirable demand-side flexibility source in distribution networks. It can participate in regulation services and mitigate power imbalances from fluctuating distributed renewable generation. To effectively utilize the load flexibility from spatiall...

Heating, ventilation, and air-conditioning (HVAC) systems play an increasingly important role in the construction of smart cities because of their high energy consumption and available operational flexibility for power systems. To enhance energy efficiency and utilize their flexibility, strategic operation is indispensable. However, finding a desir...

Thermostatically controlled loads (TCLs) are regarded as one of the promising resources for suppressing power fluctuations of renewable energy (RENs). However, due to great burdens of fully considering each users characteristics, it is difficult to achieve unity of the individual optimal consumption and global optimal scheme in demand-side manageme...

The increasing peak-valley differences, air conditioners and renewable energy sources bring new challenges to the smart grid in China. Demand response (DR) is regarded as one of the most important solutions to the above problems. A new round of electricity market reform is being carried out in China, which provides a good opportunity for developing...
