Given the fast pace of grid modernization, system states are changing more frequently and
rapidly with the high penetration of renewable energy, responsive loads and power …

The typical five-minute computational latency of current Energy Management Systems
(EMSs) can leave and has left system operators blind to the system state created by events …

As the fast growth and large integration of distributed generation, renewable energy
resource, energy storage system, and load response, the modern power system operation …

Power flow analysis plays a fundamental and critical role in the energy management system
(EMS). It is required to well accommodate large and complex power system. To achieve a …

The voltage stability is an essential security concern when a system is operating in peak
load hours or subjected to an N-1 contingency. Among various voltage stability indices …

With the development of charging technologies, the auto industry has envisioned the ability
to recharge plug-in electric vehicles (PEV) at speeds comparable to traditional gas refueling …

In this paper, a triangle count-based branch contingency screening scheme is proposed for
transmission power systems. Different triangle count algorithms are compared. A parallel …

Compared with traditional relational database, graph database (GDB) is a natural
expression of most real-world systems. Each node in the GDB is not only a storage unit, but …

The cycle structure in a power grid may lower the stability of the network; thus, it is of great
significance to accurately and timely detect cycles in power grid networks. However …

In this study, a graph-computing based grid splitting detection algorithm is proposed for
contingency analysis in a graph-based EMS (Energy Management System). The graph …
