Price-based demand response for household load management with interval uncertainty

In a smart grid, efficient load management can help balance and reduce the burden on the national power grid and also minimize local operational electricity cost. Robust optimization is a technique that is increasingly used in home energy management systems, where it is applied in the scheduling of household loads through demand side control. In this work, interruptible loads and thermostatically controlled loads are analyzed to obtain optimal schedules in the presence of uncertainty. Firstly, the uncertain parameters are represented as different intervals, and then in order to control the degree of conservatism, these parameters are divided into various robustness levels. The conventional scheduling problem is transformed into a deterministic scheduling problem by translating the intervals and robustness levels into constraints. We then apply Harris’ hawk optimization together with integer linear programming to further optimize the load scheduling. Cost and trade-off schemes are considered to analyze the financial consequences of several robustness levels. Results show that the proposed method is adaptable to user requirements and robust to the uncertainties

A Review on Wind Power Simulation Models

Wind energy has emerged as a prominent source of renewable energy due to its sustainability and low environmental impact. Efficient utilization of wind resources requires accurate prediction and modeling of wind behavior. This paper presents an overview of the most commonly adopted mathematical models employed in simulating the electrical power production of renewable wind generators. In addition, some indication of the best application is provided for each category of simulation model
