In this paper, a loss allocation approach based on modified DistFlow model is proposed. The form of the similar to simplified DistFlow. Based model, three types equations, namely, power flow network and equations are presented allocate losses. By introducing path-branch incidence matrix, all can be in analytical forms for generalized radial distribution network. results IEEE 33-bus system show that: firstly, more accurate than DistFlow; secondly, decoupling losses by within an acceptable...

Disputes over cost allocation can present a significant barrier to investment in shared infrastructure. While it may be desirable allocate way that corresponds expected benefits, investments long-lived projects are made under conditions of substantial uncertainty. In the context electricity transmission, uncertainty combined with inherent complexity power systems analysis prevents calculation an estimated distribution benefits is agreeable all participants. To analyze aspects problem, we...

The identification of transmission sections is used to improve the efficiency monitoring operation power grid. In order test validity identified, an assessment process necessary. addition, Transmission betweenness, index for finding key lines in grid, should also be verified. this paper, chain attack assumed check weak links thus verifying betweenness implemented system. Moreover, line outage distribution factors (LODFs) are quantify change flow when leading breaks down, so that can proved....

This paper presents a control reconfiguration approach to improve the performance of certain class dynamical systems. Motivated by recent research on re-engineering cyber-physical systems, we propose three-step retrofit procedure. Firstly, reverse-engineer system as gradient descent algorithm solve an unconstrained convex optimization problem. Secondly, apply heavy ball method or accelerated with constant coefficients this Finally, com-paring original and dynamics, obtain implementation...

This paper presents a control reconfiguration approach to improve the performance of two classes dynamical systems. Motivated by recent research on re-engineering cyber-physical systems, we propose three-step retrofit procedure. First, reverse-engineer system dig out an optimization problem it actually solves. Second, forward-engineer applying corresponding faster algorithm solve this problem. Finally, comparing original and accelerated dynamics, obtain implementation redesigned part (the...

This paper presents a control redesign approach to improve the performance of certain class dynamical systems. Motivated by recent research on re-engineering cyber-physical systems, we propose three-step retrofit procedure. First, reverse-engineer system dig out an optimization problem it actually solves. Second, apply augmented Lagrangian or hat-x method solve this problem. Finally, comparing original and new dynamics, obtain implementation redesigned part (i.e., extra dynamics). As result,...

Liberalized electricity markets often include resource adequacy mechanisms that require consumers to contract with generation resources well in advance of real-time operations. While administratively defined have most commonly taken the form a capacity obligation, efficient would feature broad array arrangements adapted risk profiles and appetites market participants. This article considers how financial hedge embedded alternative designs can induce different responses from risk-averse...

Energy-only electricity markets, such as the Electric Reliability Council of Texas (ERCOT), rely on decentralized investment decisions market participants to lead a resource mix providing an efficient level reliability. During exceptionally cold winter storm in February 2021, ERCOT experienced shortfalls unprecedented scale, with nearly half generation fleet experiencing outages at peak. The depth resulting blackouts invites questions regarding ability systems relying planning appropriately...
