What is a day-ahead economic dispatch framework for wind-integrated microgrids?

Scientific Reports 15, Article number: 26579 (2025) Cite this article This study proposes an optimized day-ahead economic dispatch framework for wind-integrated microgrids, combining energy storage systems with a hybrid demand response (DR) strategy to address real-time grid pricing dynamics.

What are the different power supply strategies in microgrid models?

Comparison of Power Supply Strategies in Microgrid Models: (a) Grid-only operation without renewables or DR; (b) Wind-solar generation with partial grid support; (c) Wind–solar–storage dispatch with grid coordination. Each scenario shows the evolution of load and supply coordination. Impact of Price-Based DR on Load Curve.

What is hybrid energy storage?

Hybrid energy storage (HESS) integrates power and energy advantages, which can effectively control the power over-limit, promote the consumption of wind power and photovoltaic, and relieve the PS pressure of conventional generators [9, 10].

What happens if wind or solar generation is incorporated in a microgrid?

When wind or solar generation is incorporated, the microgrid faces surplus and shortfall situations. If generation exceeds the load demand, the surplus power can be sold to the main grid; if it falls short, the deficit must be purchased from the main grid. Partial curtailment of wind and solar power is permitted under this model.

Does full integration of renewables improve microgrid stability?

Overall, the results demonstrate that full integration of renewables, storage, and demand-side participation significantly enhances microgrid stability, minimizes grid stress, and improves renewable energy utilization.

What are the different types of energy storage systems?

Firstly, different types of energy storage system (ESS) (energy-based and power-based) are unified to the joint optimal framework of peak shaving (PS), frequency containment reserves (FCR), and secondary frequency regulation (SFR).
