The integrated operation of concentrated solar power (CSP) plants and photovoltaic (PV) systems with electric heater (EH) provides a solution to minimize solar power curtailment. In this study, a two-timescale optimal dispatch strategy is proposed with a hybrid CSP-PV system, and a detailed model of the CSP plant which includes its central receiver (CR) operation mode is developed to improve the model accuracy. In the day-ahead stage, a stochastic optimal dispatch model incorporating the hybrid system is developed to account for the uncertainty of solar irradiation. An intra-day rolling optimal dispatch model including the CR operation mode is developed by adopting the proposed detailed model. The dispatch decision is adjusted on a rolling basis by integrating the intra-day ultra-short-term solar irradiation forecast with the day-ahead dispatch decision. The proposed approach is tested on the IEEE-30 bus system, and the results show that the proposed strategy guarantees the robustness of the dispatch decision with full consideration of the CR operation under the effect of short-term solar irradiation fluctuations. Furthermore, the hybrid system with the EH integration strengthens the coupling mechanism between the CSP and PV subsystems improving the efficiency and the solar energy accommodation capability.</div></div>","PeriodicalId":428,"journal":{"name":"Solar Energy","volume":"306 ","pages":"Article 114318"},"PeriodicalIF":6.0,"publicationDate":"2026-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145973404","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Photovoltaic greenhouses (PVGHs) offer a dual-use strategy by combining renewable electricity generation with controlled-environment agriculture, yet their effectiveness under extreme hot-arid climates remains underexplored. This study presents one of the first season-long empirical evaluations of controlled versus uncontrolled PVGHs in northwestern India. Tomato was selected as the test crop because of its economic importance, widespread cultivation in arid and semi-arid regions, sensitivity to heat and humidity fluctuations, and moderate shade tolerance, which allows it to benefit from partial PV shading under high-irradiance conditions. A low-cost photovoltaic (PV)-powered microclimate control system was deployed to regulate temperature, humidity, and vapor pressure deficit while sustaining electricity generation. Results show that controlled PVGHs maintained stable microclimatic conditions (23.2–27.5 °C temperature, 60–65 % relative humidity, and 0.9–1.2 kPa vapor pressure deficit), compared with wide fluctuations in uncontrolled PVGHs (18.0–40.0 °C, 40–80 % RH, and >2.0 kPa VPD). These improvements translated into stronger physiological traits, with leaf area index increasing by 1.37–1.43 times and specific leaf area by 9.2 %, resulting in a 37.9 % higher marketable tomato yield. The PV system generated ∼550 kWh during the crop cycle, exceeding control loads of ∼400 kWh and leaving a net surplus of ∼150 kWh.
