Article
Sharing economy is a distributed peer-to-peer economic paradigm, which gives rise to a variety of social interactions for economic purposes. One fundamental distributed decision-making process is coalition formation for sharing certain replaceable resources collaboratively, for example, sharing hotel rooms among travelers, sharing taxi-rides among...
Article
The {\it AC Optimal Power Flow} (OPF) problem is a fundamental problem in power systems engineering which has been known for decades. It is a notoriously hard problem due mainly to two reasons: (1) non-convexity of the power flow constraints and (2) the (possible) existence of discrete power injection constraints. Recently, sufficient conditions we...

Autonomous drones (also known as unmanned aerial vehicles) have several advantages over ground vehicles, including agility, swiftness, and energy-efficiency, and hence are convenient for light-weight delivery and substitutions for manned missions in remote operations. It is expected that autonomous drones will be deployed in diverse applications in...

Full-text available
A classical problem in power systems is to allocate in-coming (elastic or inelastic) demands without violating the operating constraints of electric networks in an online fashion. Although online decision problems have been well-studied in the literature, a unique challenge arising in power systems is the presence of non-linear constraints, a depar...

Drive modes are driver-selectable pre-set configurations of powertrain and certain vehicle parameters. Plug-in hybrid electric vehicles (PHEVs) typically feature special options of drive modes that can affect the hybrid energy source management system, for example, electric vehicle (EV) mode (that draws fully on battery) and charge sustaining (CS)...

Demand response management has become one of the key enabling technologies for smart grids. Motivated by the increasing demand response incentives offered by service operators, more customers are subscribing to various demand response programs. However, with growing customer participation, the problem of determining the optimal loads to be curtaile...
Conference Paper
Plug-in hybrid electric vehicles (PHEVs) are a viable energy-efficient means of transportation, which enjoy both convenience of fuel refilling and cheap electrical energy. But PHEVs have complex dynamics of orchestrating hybrid energy sources. While many prior results in energy management consider the internal optimization processes of PHEVs, this...

... We define two fair cost-sharing schemes, which are based on similar ideas in [8,9], and show them to be individually rational by Theorem 2. ...
... Further simulations show that our algorithm can produce close-to-optimal solutions in practice. In future work, we will study efficient algorithms for scalable network sizes [14], online arrival demands [15], and bi-criteria algorithms that can achieve better performance with a provably small violation on the constraints [16]. ...
... However, both [13] and [14] were simply expressed in relation to speed and do not contain enough information for comparisons, the lack of closed-form expression limits their applications. Besides, by analyzing the battery performance, some power consumption models for electricpowered UAVs were obtained in [15]- [17]. In order to further understand the power consumption for the UAV theoretically and improve the applicability of the models, the last category considers the theoretical-driven power consumption model by kinematic and aircraft theory [18]- [20], such as [21]- [26], for example, a generic power consumption model as a function for the UAV's velocity and acceleration was derived for fixed-wing UAVs in [21], whereas, the above results for fixed-wing UAVs cannot be applied for rotary-wing UAVs, due to their fundamentally different mechanical designs and hence drastically different power consumption models. ...
... At present, the routing optimization of electric vehicles can provide a reference for HVs [15,16]. Considering energy efficiency and charging price, an optimization model for EV fleet routing and charging was proposed in [17] to build a high-efficiency dynamic transit system. ...
... The simulation results confirm that the produced solutions do not violate network constrains and voltage levels. Recently, this work has been extended to consider scheduling, optimal power flow and online setting [32]–[34]. APPENDIX In the appendix, the full proof of Theorem 1 is presented followed by the formulation of UMDR-OPF problem. ...
... This is the architecture of the power system for a hybrid electric propulsion aircraft, and the turbine-driven generator, hybrid energy storage, fuel cell emergency system, and HVDC power system can be combined together. The power allocation and energy optimization for the airport and EPA are necessary, similar to the terrestrial microgrid and smart grid [128]. The EPA powertrains include generators, power distribution subsystems, energy storage, and several distributed propulsion motors. ...
