“…The receiver is composed of a drum, 7 evaporators and 4 superheater panels. The thermal energy storage system in the demo plant is the combination of a steam accumulator with the volume of 100 m 3 , two heat exchangers, two oil pumps, hot and cold oil storage tanks, where the artificial oil Therminol VP-1, a mixture of biphenyl ether and biphenyl, is used [3].…”

The study is carried out in the framework of cooperation between IEE-CAS and EDF R&D since 2012 on the Badaling 1MWe concentrated solar tower power plant located in the suburb of Beijing. The paper first presents a dynamic model of the power plant, in which Modelica library 'ThermoSysPro' was applied under the simulation environment Dymola ® . The model comprises sun to power generation loop and thermal storage system including two tanks oil and a steam accumulator. A detailed shell and tube steam-oil sectional heat exchanger has been modeled and implemented to simulate the heat transfer performance. By doing this, storage charging and releasing procedure could be predicted delivering transient behaviors of the upstream and downstream steam quality. A two-level control design on the Matlab/Simulink ® was developed and tested on the detailed Dymola ® model. For realizing the coupling of two simulation tools, different approaches, were attempted, among which OPC server structure is suggested and presented in detail in this paper.

A solar receiver undergoes frequent transients events and the nature of these transient events is very different from conventional thermal power plants. The SRSG (Solar Receiver Steam Generator) operates during the day when heat from the sun is available and is shut-down during the night. Along with the daily start-up and shut-down, it also undergoes various other transient events including short or long cloud events followed by hot-start, partial load transient during light cloud events, cold start-up transients (after extended shut-down events) and failure modes. The operation and control strategy for the SRSG should incorporate safe operation during all the transient events while optimizing on power generation. It is therefore important to model the SRSG and study the dynamic response of the SRSG under various transient conditions. This paper discusses modeling of Alstom SRSG using the APROS dynamic simulation platform. The paper describes in detail various components of high pressure, high temperature SRSG along with the need for transient modeling during the design phase. It provides details of various transient events that were simulated along with a discussion on the simulation results. The paper highlights the optimized modes of operation procedure developed using transient modeling along with control strategies.

“…Till now, most of researches have been devoted to study the dynamic characteristic of the solar thermal power plant. The steam-direct DAHAN tower power plant was modeled by Xu [28,29], of which the dynamic characteristics were discussed. Besides, the dynamic simulation of an indirect thermal storage tank was carried out by Li and Xu [8].…”

Concentrated solar power plant (CSP) with thermal energy storage can be operated as peak load shaving plant, which is one of the most economic solutions to the intermittency of renewable energy grid. The steam generation system (SGS) is the central hub between the heat transfer fluid and the working fluid of CSP, of which the dynamic characteristics need to be further investigated. The SGS of Solar Two power tower plant with the molten salt as both the heat transfer fluid and storage media is selected as the object. The mathematical model with lumped parameter method is developed to analyze its dynamic characteristics. Model validation is carried out and it shows that the proposed model can simulate the characteristics of SGS in an accurate manner. Five simulation tests were carried out under the disturbances that the molten salt solar tower power plant may encounter under various solar irradiation and output electrical load. Both the dynamic and static
