Grid-side Flexibility of Power Systems in Integrating Large-scale Renewable Generations: A Critical Review on Concepts, Formulations and Solution Approaches
Jia Li, Feng Liu, Zuyi Li +2
Though considerable effort has been devoted to exploiting generation-side and demand-side operational flexibility in order to cope with uncertain renewable generations, grid-side o…
Impacts and Benefits of UPFC to Wind Power Integration in Unit Commitment
Jia Li, Feng Liu, Zuyi Li +2
Unified Power Flow Controller (UPFC) is recognized as the most powerful flexible AC transmission systems (FACTS) device for power system operation. This paper addresses how UPFC ex…
Robust Coordinated Transmission and Generation Expansion Planning Considering Ramping Requirements and Construction Periods
Jia Li, Zuyi Li, Feng Liu +4
Two critical issues have arisen in transmission expansion planning with the rapid growth of wind power generation. First, severe power ramping events in daily operation due to the…
A Decomposition Based Approach for Solving a General Bilevel Linear Programming
Xuan Liu, Zuyi Li
Bilevel optimization has been widely used in decision-making process. However, there still lacks an efficient algorithm to determine an optimal solution of a bilevel optimization p…
Robust Integration of High-level Dispatchable Renewables in Power System Operation
Hongxing Ye, Jianhui Wang, Zuyi Li
The increasing penetration of Renewable Energy Sources (RES) requires more Flexibility Resources (FR), generally thermal units and storages, must be kept in the system to accommoda…
Pricing the Ramping Reserve and Capacity Reserve in Real Time Markets
Hongxing Ye, Zuyi Li
The increasing penetration of renewable energy in recent years has led to more uncertainties in power systems. In order to maintain system reliability and security, electricity mar…
Market Clearing for Uncertainty, Generation Reserve, and Transmission Reserve--Part II:Case Study
Hongxing Ye, Yinyin Ge, Mohammad Shahidehpour +1
In Part II of this two-part paper, we analyze the marginal prices derived in Part I of this two-part paper within a robust optimization framework. The load and generation are price…
Uncertainty Marginal Price, Transmission Reserve, and Day-ahead Market Clearing with Robust Unit Commitment
Hongxing Ye, Yinyin Ge, Mohammad Shahidehpour +1
The increasing penetration of renewable energy in recent years has led to more uncertainties in power systems. These uncertainties have to be accommodated by flexible re- sources (…
