Abstract
A concentrated solar power (CSP) plant with energy storage systems has excellent scheduling flexibility and superiority to traditional thermal power generation systems. In this paper, the operation mechanism and operational constraints of the CSP plant are specified. Furthermore, the uncertainty of the solar energy received by the solar field is considered and a robust economic dispatch model with CSP plants and renewable energy resources is proposed, where uncertainty is adjusted by the automatic generation control (AGC) regulation in the day-ahead ancillary market, so that the system security is guaranteed under any realization of the uncertainty. Finally, the proposed robust economic dispatch has been studied on an improved IEEE 30-bus test system, and the results verify the proposed model.
Highlights
Due to the explosive growth of the world and industry, energy consumption is increasing rapidly.Traditional fossil energy is challenged to meet the increasing needs of future society [1]
The specific parameters of the concentrating solar power (CSP) plants and automatic generation control (AGC) units are shown in Table 1, and the maximum output of the PV power is set to 200 MW, and the wind farm is set to 40 MW for each
A case study was carried out on the improved IEEE 30bus test system and it can be concluded that compared with the PV power plant, the CSP plants have a stable output and high operating efficiency and can participate in the reserve market
Summary
Due to the explosive growth of the world and industry, energy consumption is increasing rapidly. With the large-scale access to renewable energy, its intermittent characteristics have brought severe challenges to the safe operation and reasonable scheduling of the power grid, resulting in large-scale curtailed wind and photovoltaics in actual production. Reference [25] proposed the detailed model of CSP plants, which can be used in economic dispatch, and utilized two different state machine models to describe the operation state of the turbine. A joint robust economic dispatch of a CSP plant with wind and photovoltaic generation is proposed, which contains detailed modeling for day-ahead power system dispatch to address the uncertainties from renewable energy generation while guaranteeing the safety constraints for any possible uncertainty parameter fluctuations. (iii) To address the uncertainty from renewable energy, a robust scheduling model for the CSP plant is further proposed with participation in market reserve and AGC regulation.
