Abstract
Renewable energy-based electricity production made significant progress in the recent past, and in the future it is expected to have a considerable contribution in power generation demography. A persistent need of renewable energy and the slow retirement of less efficient thermal power plant is inevitable. However, the variation in renewable production poses a challenge to a smooth and stable operation of a power grid. Hence, the operability of a nonrenewable energy power plant, especially a thermal power plant, plays a crucial role in the successful integration of renewable and stable grid operation. Systems and control aspects like modeling, estimation, prediction, and optimization play an important role in successfully tackling and improving the reliability and availability of a future electrical ecosystem. This chapter gives an overview of the challenges and opportunities for control systems from the perspective of steam-based power plants, particularly boiler operability in lieu of renewable energy integration. Also, a case study of exploring robust MIMO (Multi-Input-Multi-Output) control during a part load of a boiler with bypass control is presented. This scenario is expected to be common during renewable integration.
