Improvement of Flexibility in the Integrated Energy Systems

This paper presents possibilities to improve flexibility for integrated energy systems using optimization techniques in a capacity market. Long-term planning of the energy system is considered. Meeting the rapidly growing demand for electricity requires a complete integrated power system solution that must support consumers, stakeholders, and regional operations. The rapid change in the global economy is creating an energy transition towards the strategic future of power systems and energy markets - a new era of flexible grids, or the era of energy flexibility. The proposed capacity market model improves the competitiveness of the energy market system in accordance with the assessment and flexibility of electricity security. It also presents recommendations for evaluating the dimensions of the integrated energy system. All participants in the energy market can accept it as a useful tool to support decision-making and increase the sustainability of the energy system. The smart grids provide the reliability of power supply in an increasingly complex operating environment, achieved through observability, digitalization, and an increase in the number of measurements. Power supply and grid companies remain the main drivers of change.
