This work assesses the participation of wind power plants in primary frequency control support. To participate in frequency control-related tasks, the wind power plants have to maintain a certain level of power reserves. In this article, the wind power plant is equipped with a flywheel-based storage system to fulfil the power reserve requirements set by the network operator. The article focuses...

We propose a stochastic model for the daily operation scheduling of a generation system including pumped storage hydro plants and wind power plants, where the uncertainty is represented by the hourly wind power production. In order to assess the value of the stochastic modeling, we discuss two case studies: in the former the scenario tree is built so as to include both low and high wind power p...

The increasing wind power penetration in power systems represents a techno-economic challenge for power producers and system operators. Due to the variability and uncertainty of wind power, system operators require new solutions in order to increase the controllability of wind farm output. On the other hand, producers that include wind farms in their portfolio need to find new ways to boost the...

The study provides a on energy storage technologies for photovoltaic and wind systems in response to the growing demand low-carbon transportation. Energy (ESSs) have become an emerging area of renewed interest as critical factor renewable systems. technology choice depends essentially system requirements, cost, performance characteristics. Common types ESSs sources include electrochemical (batt...

Abstract In the context of determination and implementation dual carbon goal, it is an important trend China’s energy strategy to incorporate a considerable proportion renewable into power grid. Therefore, consumption gradually turning new sources such as wind energy. Considering limitations random, intermittent anti-peak regulation forms light, multi-objective optimization model wind, fire sto...

The paper addresses the unit commitment problem in power plant operation planning. For a real power system comprising coal and gas red thermal as well as pumped storage hydro plants a large-scale mixed integer optimization model for unit commitment is developed. Then primal and dual approaches to solving the optimization problem are presented and results of test runs are reported.

The unit commitment prob lem in a power generation system com prising thermal and pumped storage hy dro units is addressed A large scale mixed integer optimization model for unit commitment in a real power system is de veloped and solved by primal and dual ap proaches Both solution methods employ state of the art algorithms and software Results of test runs are reported
