In this paper, we propose a convex planning model of integrated heat and electricity systems considering variable mass flow rates. The main challenge comes from the non-convexity o…
A Quadratic Convex Approximation of Optimal Power Flow in Distribution System with Application in Loss Allocation
Tianshu Yang, Ye Guo, Lirong Deng +2
In this paper, a novel quadratic convex optimal power flow model, namely, MDOPF, is proposed to determine the optimal dispatches of distributed generators. Based on the results of…
A Linear Branch Flow Model for Radial Distribution Networks and its Application to Reactive Power Optimization and Network Reconfiguration
Tianshu Yang, Ye Guo, Lirong Deng +2
This paper presents a cold-start linear branch flow model named modified DistFlow. In modified DistFlow, the active and reactive power are replaced by their ratios to voltage magni…
Stochastic Unit Commitment in Electricity-Gas Coupled Integrated Energy Systems based on Modified Progressive Hedging
Haizhou Liu, Xinwei Shen, Qinglai Guo +3
The increasing number of gas-fired units has significantly intensified the coupling between power and gas networks. Traditionally, the nonlinearity and nonconvexity in gas flow equ…
Reconfiguration of District Heating Network for Operational Flexibility Enhancement in Power System Unit Commitment
Yixun Xue, Mohammad Shahidehpour, Zhaoguang Pan +4
Massive adoptions of combined heat and power (CHP) units necessitate the coordinated operation of power system and district heating system (DHS). Exploiting the reconfigurable prop…
Increasing the Flexibility of Combined Heat and Power Systems through Optimal Dispatch with Variable Mass Flow
Xin Qin, Ye Guo, Xinwei Shen +1
In combined heat and power systems, varying mass flow can better make use of the heating system inertia to increase the flexibility of electric power systems. This is challenging,…
