Heat Demand

The integration of a thermal storage system into the solar heating system enables to increase the use of solar thermal energy in buildings and allows avoiding the mismatch between consumers’ demand and heat production in time. The paper presents modelling a seasonal thermal storage tank various sizes of which have been analyzed in the district solar heating system that could cover a part of heat demand for the district of individual houses in Vilnius. A biomass boiler house, as an additional heat source, should allow covering the remaining heat demand. energyPRO software is used for system modelling. The paper evaluates heat demand, climate conditions and technical characteristics. Santrauka Šilumos akumuliavimo sistemos integracija į saulės šildymo sistemą suteikia galimybę padidinti Saulės šiluminės energijos panaudojimą pastatuose, nes tai leidžia išvengti vartotojų poreikio ir šilumos gamybos nesutapimo laike. Šiame darbe modeliuojama sezoninė šilumos akumuliacinė talpykla, analizuojami įvairūs jos dydžiai centralizuotoje saulės šildymo sistemoje. Nagrinėjama sistema galėtų užtikrinti dalį individualių namų mikrorajono, esančio Vilniuje, šilumos poreikių. Kaip papildomas šilumos šaltinis modeliuojama biokuro katilinė, kuri leistų užtikrinti likusią šilumos poreikių dalį. Modeliavimas atliekamas energyPRO programa įvertinant pastatų poreikius, klimatines sąlygas ir technologines įrenginių charakteristikas.

Operation Flexibility

The growing penetration of wind power in a power system brings great challenges to system operation flexibility. For generation planning in presence of high wind power penetration, it is essential to take the operation flexibility of the system into account. Firstly, this paper developed the system operation flexibility metrics through considering the flexibility contribution of thermal generating units (TGUs) by operational state transition. Secondly, a planning model for the bundled wind-thermal-storage generation system (BWTSGS) that considers the operation flexibility constraints is proposed. The planning model is used to determine the power and energy rating of an energy storage system (ESS) as well as the type and number of TGUs. A daily scheduling simulation model of a BWTSGS is proposed to calculate the operation cost for the planning model and consider the sequential operation characteristics of the BWTSGS. Further, in order to accelerate the computation, a wind power sequential clustering technique based on the discrete Fourier transform (DFT) method is developed for improving the computational efficiency. Case studies have been conducted on a 1000-MW wind farm to demonstrate the validity and effectiveness of the proposed model.

Melting And Solidification

The present study explores suitability of two phase change materials (PCM) for development of an active thermal storage system for a solar drying kiln by studying their melting and solidification behaviors. A double glass glazing prototype solar kiln was used in the study. The storage system consisted of a water storage tank with PCM placed inside the water in high density polyethylene containers. The water in the tank was heated with help of solar energy using an evacuated tube collector array. The melting and solidification temperature curves of PCM were obtained by charging and discharging the water tank. The study illustrated the utility of the PCM in using the stored thermal energy during their discharge to enhance the temperature inside the kiln. The rate of temperature reduction was found to be higher for paraffin wax as compared to a fatty acid based PCM. The water temperature during the discharge of the PCM showed dependence on the discharge characteristics of each PCM suggesting their suitability in designing active thermal storage systems.
