“…Nevertheless, the growing tendency to RESs such as solar energy and wind power has caused new challenges in operation and planning of power systems. These issues are primarily emerged as a result of the stochastic and intermittent nature of RESs that should be taken into account by system operator in operational management process [2,3].…”

“…In the power system, with the rapid development of distributed generation, user-side management has become an important way to improve system flexibility (Rashidizadeh-Kermani et al, 2020). To assess the operational flexibility capacity of the system, a fixed robust uncertainty set and an adjustable uncertainty set were constructed; the wind power model based on a two-stage robust unit commitment was introduced in Pourahmadi et al (2022), and the author adopts the improved method based on the CCG algorithm to solve the adjustable robust model. Considering energy storage and reserves, Zhang et al (2016) presented a flexibility-oriented unified scheduling model to study the features required for flexibility assessment.…”

In order to help achieve the goal of carbon peak and carbon neutrality, the large-scale development and application of clean renewable energy, like wind generation and solar power, will become an important power source in the future. Large-scale clean renewable energy generation has the uncertain characteristics of intermittency, randomness, and volatility, which brings great challenges to the balance regulation and flexible operation of the power system. In addition, the rapid development of renewable energy has led to strong fluctuations in electricity prices in the power market. To ensure the safe, reliable, and economic operation of the power system, how to improve the power system flexibility in an uncertain environment has become a research hotspot. Considering the uncertainties, this article analyzes and summarizes the research progress related to power system flexibility from the perspective of power system planning, operation, and the electricity market. Aiming at the modeling technology of uncertainty, the related modeling methods including stochastic programming, robust optimization, and distributionally robust optimization are summarized from the perspective of mathematics, and the application of these methods in power system flexibility is discussed.

“…Multivariate statistical analysis based methods such as "flying-brick" have been developed to deal with variable requirements of the look-ahead generation capacity, ramping capability, and ramp duration for unit commitment problems. For more details see Pourahmadi et al (2020). We focus on Interval Optimisation approach developed for unit commitment problems by Wu et al (2012).…”

As a powerful analytical method, optimisation has been used for energy planning problems for a long time. Recent developments in computational capabilities have made it possible to include complex assumptions such as integration of natural gas and power networks, and uncertainty of various parameters with reasonable details in one energy planning problem. It is important to study the integrated natural gas and power networks to reduce the impact of variation in power generation of renewable sources. Moreover, advantages of renewable energy resources have been encouraging many countries to assign a large share of their energy portfolio to these resources. Due to uncertainty, finding a reliable and secure combination of technologies including thermal and renewable sources is significantly complicated. Approaches such as chance constrained programming and robust optimisation have been used to handle reliability and uncertainty of renewable resources and demand.Non-linearity of natural gas network leads to complex energy planning problems. In order to provide a practical pathway to carry out an energy planning problem, we categorise and discuss important topics in energy planning under three main subjects: problem settings and model, uncertainty and solution methods. We suggest a relatively comprehensive optimisation model which includes key features of an integrated power generation and transmission expansion plan and natural gas network. Then, to deal with uncertainty of net load and equipment failure, we suggest robust optimisation and a cutting planebased method. Finally, we review solution methods used to solve similar problems.
