“…The ISO/RTO generally presents a revised commitment with a focus on reliability following the clearing of the DA market and before the initiation of the operating day. The post‐DA reliability assessment commitment (RAC) is additionally operated together with SCUC [ 93 ] . While the conditions of generating units may vary considering the possible outages, the demand bids are now replaced with the forecasted load for the next day.…”

Wind energy generation is a fast developing efficient renewable source widely used for modern power generation. [1] Countries and energy companies have increased their interest in electricity generation from wind energy in the last decades, thanks to its natural, cost-free, and environmentally friendly features. [2] Wind power plants can generate electrical energy at any time of the day and are distributed energy sources for systems that need permanent energy. [3] Nonetheless, due to the disordered nature of the earth's atmosphere, there is a major uncertainty in the electrical power produced by the wind, which causes complexities in the utilization and management of wind energy sources. [4] The changes in weather conditions depending on time and location also create uncertainty in managing the supply-demand balance controlled by the grid operators. [5] In cases where the electrical energy produced by wind power plants is insufficient, auxiliary energy sources provide operational support to the electric grid. [6] Ensuring the supply-demand balance in the electricity grid is also an important condition for the electrical power quality and energy supply in the transmission system, and wind power plant operators care about the follow-up of wind power in terms of economy, operation, and planning. [7] For this, the presence of wind power forecasting (WPF) is an essential factor in the optimization of wind power plants. [8] For consumers to use electrical energy uninterruptedly, efficiently, and economically, wind power plant operators need to estimate the generated electrical energy smoothly. [9] The smooth estimation of electrical power generated by wind turbines increases the operational efficiency for system maintenance, planning, investment, and energy traders. [10,11] It is a precious procedure for electrical grids to provide a respectable commercial yield on the electrical energy market. [12] The capability of advanced WPF provides the contributions like balancing the power system and mitigation of penalties, scheduling the maintenance of wind power plants, investment regarding site location, and technoeconomic and socioeconomic benefits. [13,14] In this way, it is possible to reduce the energy cost and obtain high revenue in the energy market as a result of the contributions obtained for wind power generation systems. [15]

“…Limitations (8) and ( 9) limit the allocation of high and low storage capacity of gas units, separately. The same limit is added for the high and low storage capacity of the thermal units in (10) and (11), respectively. Limitations ( 12) and ( 13) indicate the fuel demand for any gas unit and the relevant capacity for the pipeline, correspondingly.…”

“…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.…”

“…In [9], a common network hardware and gas optimization is suggested to assess and strengthen network overhead power feeders and underground gas transmission lines beside unexpected events. In [10], manufacturers need to exploit their high-level profits over market equilibrium in low-level power market and gas ventilation. In this manner, gas and PtG units may provide strategic solutions for the main grid.…”

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.
