“…NOWADAYS, 13 high voltage DC (HVDC) transmission projects have been built in China [1][2][3], including three ultra HVDC (UHVDC) transmission projects (Fufeng UHVDC project, Jinsu UHVDC project, and Binjin UHVDC project). These three UHVDC transmission projects delivery 21.6 million kilowatts power from Sichuan province to the East China Power Grid, which are responsible for more than 80% of Sichuan's hydropower transmission task, accounting for two-thirds of the received power in East China.…”

The existing relay protections for line‐commutated converter (LCC)‐ultra high voltage DC (UHVDC) transmission lines are insufficient in protection sensitivity and operation speed. The travelling wavefront fault distance information can be used to improve protection performance, which has been used in protection of voltage source converter ‐high voltage DC (HVDC) transmission lines. The adaptability of travelling wavefront protection in LCC‐UHVDC transmission line is analyzed in this paper. First, the conditions that need to be met for the travelling wavefront protections to be able to effectively recognize faults are analyzed. Eight applicability conditions of wavefront protection are revealed from the perspective of travelling wavefront generation and practical application requirements. Then the degree of match between the applicability conditions and the conditions of LCC‐UHVDC system is analyzed as a basis for assessing the adaptability of travelling wavefront protection in the LCC‐UHVDC system. It is pointed out that the index coefficient‐based wavefront protections are not available for LCC‐UHVDC transmission lines since the hardware sampling rate of protection device is insufficient, while first peak time of transient voltage (FPTV)‐based wavefront protection is available for LCC‐UHVDC transmission lines if it has enough anti‐noise ability. Finally, an enhanced anti‐noise algorithm is proposed for the FPTV‐based travelling wavefront protection. The adaptability of the travelling wavefront protection is verified by hardware‐in‐the‐loop test and filed recording experimental data.

“…The UC problems can be classified into different subgroups in a few ways [1]. With respect to security constraints, UC problems can be divided into conventional UC problems and security-constrained UC (SCUC) problems [2], [3]. According to whether uncertainty is considered and whether the probabilistic distribution of uncertain parameters…”

“…Linearization of non‐convex gas constraints lets authors mix the problem into a correct linear program by means of a combination of approximate functions of indeterminate limits. In [6], a joint decentralized power and gas grid planning is offered to increase the transaction capability and reduce the communication load. For this purpose, they used the I‐ADMM technique to handle non‐convex gas grid constraints.…”

“…This growing penetration of gas units in power grids depends on the safe management of the grid and the amount of access to natural gas [1]. The effects of natural gas on the quality of the main grid have been studied in several recent articles [2][3][4][5][6][7][8][9][10]. In [2], the researchers suggest a two-level maximum revenue for both the power and gas markets individually, in which local marginal costs are reorganized at lower levels of market clearance and members in both markets.…”

This research work tries to investigate the provision of flexibility on both sides of production and demand security constraint unit commitment (SCUC) before the schedule is considered. To this end, a powerful heuristic technique based on modified firefly algorithm (FA) is devised to achieve the optimal solution. Moreover, fast-starting gas units (FGUs) are considered as providers of lateral flexibility as a result of their quickness in starting work and high ramp capability. Considering the fact that the normal operation of units is subject to the supply of reliable gas through connected gas transmission lines, the uncertainty of gas supply in the suggested model is considered to imitate the effects of deviation in the volume of gas over pipelines. The application of the suggested model has been tested on IEEE-118 bus.
