Special Issue Information

Dear Colleagues,

The use of renewable energy sources makes it possible to reduce the consumption of traditional hydrocarbon energy carriers, which is a global priority direction for the development of science and technology. The integration of renewable energy sources (RES) into power grids is a significant global trend impacting various problems in specific conditions of particular countries. To operate RES more reliably and affordably, new digital decisions need to be proposed. The implementation of DT in RES to manage their day-to-day operations and optimize performance increases efficiency and speeds up the binding target of the EU outlining that the share of electricity produced by renewables must grow to 50% by 2030.

The aim of this Special issue is to study the digitalization of Renewable Energy Sources (RES), creating Digital Twins (DTs), supporting the balancing of the power grid and increasing the flexibility of the energy system, possible through dispatchable renewable energy sources.

For this Special Issue, original research articles and reviews are welcome. Research areas may include (but are not limited to) the following:

  • Implementation of renewable energy sources
  • Analysis of available technical means
  • Development of technological schemes implementation RES in the power grid
  • Simulation photovoltaic system
  • Conditions for stable operation of microgrids together with centralized networks;
  • Formation of practical recommendations for the construction of energy supply systems of multi-purpose objects based on renewable energy.
  • Model microgrid with renewable energy sources
  • DT microgrid and RES
  • Formation of optimal parameters of the power supply system according to the criterion of cost minimization and energy efficiency
  • Developing the composition of equipment (the number, type, and location of electrical modules, inverters, and storage systems, taking into account the terrain and meteorological conditions)
  • Using modern software for simulation RES
  • Degradation PV module

We look forward to receiving your contributions.

Assessing market power in the presence of different production technologies such as renewable energies, including wind and solar power, is crucial for electric market analysis and operation. This paper investigates structural market power by incorporating wind farms and solar generation over a short-term period. The study examines the issue of market concentration boundaries to assess structural market power by calculating the minimum and maximum market concentration index values in the day-ahead market. It models the technical specifications of power plants, such as the maximum and minimum production limits, ramp-up and ramp-down rates, and minimum required up and down times. By extracting the spatiotemporal correlation of wind power generation from real data, the uncertainty of renewable power generation is represented through a set of scenarios. The analysis explores the correlation effects of wind farms, solar generation, and wind penetration levels under different ownership structures. Simulation results using a modified PJM five-bus system illustrate the effectiveness of the developed method. Our results indicate that integrating renewable energy can reduce the Herfindahl–Hirschman Index (HHI) by up to 30% as wind penetration levels rise from 0% to 40%, fostering a more competitive market structure. However, the correlation between wind farms also increases market volatility, with the standard deviation of the HHI rising by about 25% during peak load periods. These findings demonstrate the practical applicability of the developed methodology for assessing market dynamics in the presence of renewable energy sources. Full article

Currently, the proportion of enterprise self-owned power plants (SPPs) is increasing, with a significant share occupied by small coal-fired units, severely affecting the absorption of new energy and causing substantial pollution. To address this issue, developing generation rights trading between SPPs and new energy enterprises is an effective solution. At present, research on generation rights trading is mainly based on early water and thermal generation rights replacement trading. This approach, to some extent, overlooks changes in electricity market policies. Based on this, a new generation rights trading bidding strategy incorporating price differences and time-of-use pricing settlement is proposed. Firstly, the relationship between price difference settlement and generation rights trading is studied and the win–win model of generation rights trading is improved. Secondly, in the time-of-use pricing settlement mode, the single bidding strategy is optimized with the objective of maximizing the total social benefits in the win–win model. Finally, an example analysis compares different bidding strategies under time-of-use pricing settlement. Even in the most extreme cases, the time-of-use bidding strategy can improve social benefits by 5.61% and reduce wind and solar curtailment by 7.25% compared to the single bid strategy. The results show that the optimized time-of-use bidding strategy significantly improves the efficiency of generation rights trading, greatly helping to promote the absorption of new energy and alleviate wind and solar power curtailment.

With the development of the electricity spot market, pumped-storage power stations are faced with the problem of realizing flexible adjustment capabilities and limited profit margins under the current two-part electricity price system. At the same time, the penetration rate of new energy has increased. Its uncertainty has brought great pressure to the operation of the power system. The ramp market and its market mechanism have emerged as the times require. To this end, this article proposes a bidding strategy for pumped-storage power stations to participate in multi-level markets such as the ramp market. Considering the demand calculation of ramping services, a two-layer model of pumped storage’s participation in multiple markets is constructed. The upper level makes trading decisions with the goal of maximizing pumped-storage revenue; the lower level aims to minimize the total social cost and jointly clears the primary and auxiliary markets. The income from pumped storage participating in the main energy and ramp-up auxiliary markets at the same time is significantly higher than the income from the two-part electricity price system. Its flexible adjustment ability can be quantified, reducing dependence on capacity electricity charges and providing a theoretical reference for cost recovery and profitability of future pumped-storage power stations.
