Use of the Renewable and Waste Energy Sources in Heat Storage Systems Combined with ORC Power Plants
Published by Piotr KOLASIŃSKI, Politechnika Wrocławska, Instytut Techniki Cieplnej i Mechaniki Płynów, Zakład Termodynamik Abstract. ORC systems are mainly powered from waste and renewable energy sources. In many cases this type of energy sources are specified by the dynamic capacity and thermal characteristics. Such situation has negative influence on ORC power plant working conditions. InContinue reading “Use of the Renewable and Waste Energy Sources in Heat Storage Systems Combined with ORC Power Plants”
A Grid-Connected PV Power System Total Considers the MPPT and SSRF-SPLL Control Technologies
Published by Liu Liqun, Liu Chunxia*, Taiyuan University of Science & Technology Abstract. At present, an optimal maximum power tracking (MPPT) and grid-connected control methods for a PV power system are very important to improve the output efficiency. However, most of literatures only introduce the MPPT or PLL method, respectively. A novel MPPT method isContinue reading “A Grid-Connected PV Power System Total Considers the MPPT and SSRF-SPLL Control Technologies”
