With the exploration of deep decarbonization around world, it has become a broad consensus that carbon trading mechanism can promote low-carbon operation energy system by exploring underlying driver emissions. The end-users, as motivator emission in integrated electricity-gas (IEGS), have not been developed so far to participate market and help emissions abatement. This paper proposes bi-level scheme on demand side considering consumption level users response. In upper-level market, an...

With the exploration of deep decarbonization around world, contradiction between low-carbon operation and energy supply in systems has been aggravating. There is an urgent need to tap interactive potential source demand sides. In view current lack efficient incentive measures for consumption, integrated response exchange (IDRX) mechanism proposed promote coordinated dispatching on source-demand side electricity-gas system (IEGS). The value model IDRX emission reduction built measure ability...

With the increasing number of electric vehicles and emergence vehicle-to-grid technology, have become distributed loads power sources with random movement characteristics in distribution network.

The integration of the variable renewable energies makes operation conditions power system ever-changeable. Consequently, operational reliability evaluation is increasingly important. This paper introduces concept decision-dependent uncertainty (DDU) in evaluation. Unlike exogenous uncertainties, DDU reveals that decisions could significantly affect resolution uncertainties which influence metrics. In this paper, proposed modeling method links device indices, i.e., forced outage rate, and...

The continuous-time model is widely used to design load frequency control (LFC) schemes for power systems with delays and demand response (DR). In practice, however, the LFC system works in a sampled-data manner. plant operates continuously while updates every few seconds. This paper focuses on DR delay. Based linear quadratic regulator (LQR) theory, an optimal scheme designed regulate generation units LQR controller can be applied constant time-varying delays, regardless of DR. An observer...

The ever-increasing penetration of renewable generation is demanding additional flexibility for the operation power systems. In this sense, it has been proved that wind generators (WPGs) can provide part required operating reserve through pitch angle control (PAC) under a deloaded strategy. Unlike conventional sources, however, provided by WPGs can't always be considered reliable, which renders system dispatch more challenging. research, capacity modeled considering decision-dependent...

As the share of wind power in systems continues to increase, limited predictability generation brings serious potential risks system reliability. Previous research works have generally described uncertainty forecast errors (WPFEs) based on normal distribution or other standard models, which only characterize aleatory uncertainty. In fact, epistemic WPFE modeling due data and knowledge should also be addressed. This paper proposes a multi-source information fusion method (MSIFM) quantify...
