Risk-constrained optimal scheduling with combining heat and power for concentrating solar power plants

Dynamic frequency control strategy for the CSP plant in power systems with low inertia

“…The CSP technologies utilize a solar field (SF) of sun-tracking heliostats to capture direct normal irradiance (DNI), and thermal energy storage (TES) is employed to offer a valuable energy capacity without increasing uncertainty [12,13]. The working principle of power generation in the CSP plant is to produce high-pressure superheated steam to drive the synchronous generator connected to steam turbines to generate electricity, and energy is transferred between SF, TES, and power block (PB) by heat transfer fluid (HTF) [18]. In places where there is abundant solar radiation, such as the western region of Texas in the United States and the northwest region of China, CSP plant has a promising development prospect.…”

Day-ahead offering strategy in the market for concentrating solar power considering thermoelectric decoupling by a compressed air energy storage

“…By integrating with CSP, thermal storage system (TES) enables it to produce full power capacity even in some hours without solar power, which provides flexible scheduling characteristics for CSP plant [12].TES improves thermal comfort, reduces battery storage especially in island mode and makes smoother the heat load profiles by providing the ability of flexible supplement of electrical and thermal loads [13]. By adding combined heat and power (CHP) to CSP-TES, the strategy of generating electricity and heat simultaneously via the waste heat in exhaust steam, improves the energy resource utilization and thus make CSP investment profitable, given high initial investment cost of CSP [14,15]. As a result, improving the use of CSP as a energy resource help to implement the CSP-TES-CHP energy system and exploit the CSP advantages proved in the previous relevant researches.…”

“…Refs. [14,15] use a CHP (BT) unit integrated with CSP-TES to increase system efficiency by waste heat utilization. The presented combined heat and power scheduling provides both electrical and thermal loads simultane-ously.…”

“…The constraints of power ramping of the CSP-CHP unit are also implemented by Eqs. ( 12)- (15). In Eq.…”

Optimal Dispatch of Wind Power, Photovoltaic Power, Concentrating Solar Power, and Thermal Power in Case of Uncertain Output

“…In reference [15], through the joint optimization of power grid unit combination and technological transformation plan considering transmission and distribution synergy, the joint optimization model of unit combination and technical transformation plan of transmission network and distribution network is constructed, respectively. Reference [16] considered the uncertainty in the outputs of wind and solar power in a variety of generation systems for renewable energy and used robust stochastic optimization theory to convert the constraints on the random variables into constraints that could reflect the system manager's attitude toward risks to the system. An optimal stochastic scheduling model for multi-source power generation systems with dual robustness coefficients was then established.…”
