A suitable probabilistic scenario set of load demand and natural characteristics of renewable energy is becoming a crucial issue in power system planning studies. Properly addressing the impact of potentially thousands of residential PV plants on the…
In integrated energy systems (IESs), traditional fixed time-interval dispatching scheme is unable to adapt to the need of dynamic properties of the transient network, demand response characteristics, dispatching time scales in energy subsystems and…
Compared with coal-fired thermal units, renewable energy resource, i.e. wind energy, has the advantages of low cost and low pollution. However, wind energy has inherent uncertainty, thus resulting in “wind abandonment” and “low utilization efficiency…
The micro turbine (MT) is scheduled to catch up wind power uncertainty and thus lead to great variations in the state of natural gas system (NGS). To meet this challenge, firstly, a dynamic model of gas-electricity combined system with wind power is…
With the development of gas-fired turbines and the emerging power-to-gas (P2G) technologies, power systems and natural gas systems have been becoming more interactional. To study the integrated energy system and improve its operating efficiency, this…
The rapid increase of renewable generation and its anticipated continued growth requires greater operational flexibility in modern power systems. Previous studies explored the addition of more flexible resources to improve system flexibility, but…
An islanded DC Microgrid comprises dispatchable and renewable generation units, battery energy storage systems, and loads. An islanded DC microgrid presents several operational challenges due to load and renewable generation fluctuations. Therefore,…
Power systems with large scale integration of inverter interfaced generation plants become vulnerable to short term frequency instability. The short term frequency stability is related to limiting the RoCoF and frequency nadir within acceptable…
The flexibility of integrated energy system (IES) is restricted by the thermoelectric ratio constraints of cogeneration unit, especially for accommodating anti-peak-regulation of wind power. In this paper, a day-ahead IES optimal dispatch considering…
With the fast development of Internet of Things (IoT) especially for smart grid and electric vehicle (EV) networking, vehicle-to-grid (V2G) communications have been increasingly studied and recognized as one of the most convincing tools for general…
This article proposes an innovative integrated power and hydrogen distribution system (IPHDS) restoration model in response to multiple outages caused by natural disasters. During the restoration, repair crews and mobile battery-carried vehicles are…
