Solar Thermal Electric Plants

IEC TS 62862-2-1:2021 defines the requirements and the test methods for the characterization of thermal energy storage (TES) systems. This document contains the information necessary for determining the performance and functional characteristics of active direct and indirect thermal energy storage systems based on sensible heat in solar thermal power plants using parabolic-trough collector, Fresnel collector or tower central receiver technology with liquid storage media.
This document includes characterization procedures for testing energy storage system charge and discharge, as well as reporting the results. Test performance requirements are given and the instrumentation necessary for them, as well as data acquisition and processing methods and methods for calculating the results and their uncertainties.

IEC TS 62862-1-3:2017(E) defines a data format for meteorological data sets. The goal of this document is to reduce efforts for data exchange and to avoid errors caused by misunderstandings due to the application of various different and at times unclear formats.

IEC TS 62862-1-2:2017(E) defines the procedures for the creation of annual solar radiation data sets (ASR) for solar thermal electricity (STE) plant simulation. This document defines procedures needed for the ASR construction as well as its components and parameters. The scope of application of this document refers to the needs associated with solar thermal power plant projects and mainly related to the simulation of an annual period with a solar radiation sum close to a normal annual value (from among an estimation of all possible annual values).
