“…The proposed series multi-step approach can be easily expanded to other problems like planning [8], economic dispatch [39], and energy market [21]. Further researches will include the transient gas flow model, deep focusing on ESs operation, and expanding this method for long term operation.…”

“…[4] minimized co-planning costs in an interconnected power and NG system. Among all types of primary energy systems, the NG network has proper interdependency specifications [8]. From this point of view, employing an integrated approach offers solutions to overcome some of the energy concerns such as environmental damage associated with the use of fossil fuels, power shortage, economic issues [1].…”

Power to gas units and gas turbines have provided considerable opportunities for bidirectional interdependency between electric power and natural gas infrastructures. This paper proposes a series of multi-step strategy with surrogate Lagrange relaxation for operation co-optimization of an integrated power and natural gas system. At first, the value of coordination capacity is considered as a contract to avoid dysfunction in each system. Then, the uncertainties and risks analysis associated with wind speed, solar radiation, and load fluctuation are implemented by generating stochastic scenarios. Finally, before employing surrogate Lagrange relaxation, the non-linear and non-convex gas flow constraint is linearized by two-dimension piecewise linearization. In the proposed procedure, constraints for energy storages and renewable energy sources are included. Two case studies are employed to verify the effectiveness of the proposed method. The surrogate Lagrange relaxation approach with coordination branch & cut method enhances the accuracy of convergence and can effectively reduce the decisionmaking time.

“…At a deeper level, a distributed optimization method for reactive power optimization control is proposed, which shows the good information privacy of its distributed method [12]. A decomposition method based on the ADMM has been proposed to guarantee the gas system's data privacy while achieving the benefits of the co-planning work, ADMM algorithm has a significant role in ensuring data privacy [13]. Therefore, considering the protection of data privacy under the fair competition of various stakeholders has also become a factor that cannot be ignored in the dispatching process [14].…”

Nowadays, distributed power generation is highly valued and fully developed since the energy crisis is worsening. At the same time, the distribution system operator is becoming a new stakeholder to take part in the dispatch of the active distribution network (ADN) with the power market being further reformed. Some new challenges to the dispatching of the ADN are brought by these distribution system operators (DSO), which break the traditional requirement of the lowest operating cost. In this paper, the relationship between the maximum revenue and the minimum operating cost of the ADN is fully considered, and the model of the bi-level distributed ADN considering the benefits and privacy protection of multi-stakeholder is established precisely. Further, the model is solved by using the alternating direction method of multipliers (ADMM) in which the safety and economy of the ADN are fully considered. Finally, the validity of the model and the feasibility of the algorithm are verified by using the adjusted IEEE 33 bus.

Flexibilities offered by gas-fired power plants have strongly increased their usage in power systems. Increasing the penetration rate of gas-fired power plants has made it necessary to coordinate gas network expansion planning with electricity network expansion planning. In this paper, a decentralized model for expansion of gas and electricity networks is introduced that coordinates investment in these networks while taking into account their privacy.Alternating direction method of multipliers is used to decompose the centralized gas and electricity expansion problem into two separate expansion prob-
