Increasing penetration of intermittent renewable energy production in power systems will remarkably increase the need flexible and controllable generation. As numerous existing thermal generation units have been closed down, all possible flexibility available should be harnessed to stabilize systems. Combined heat (CHP) is widely used district heating (DH) total into DH network needs balanced with consumption, this sets significant limitations long-term production. However, load electric can...
Fluctuating power production in combined heat and (CHP) plants may cause unwanted disturbances district heating (DH) systems. DH -systems are often automated, however, supply temperature (ST) is still primarily chosen manually by the operator because of uncertain demand near future delay from supplier to consumers. In this work, return water predicted based on outdoor forecast process data history using neural network estimators. Consumers presumed be similar, but their distances site vary...
Climate change and global economic pressures are strong drivers for energy economies to transition towards climate-neutrality, low-carbon economy better resource efficiencies. The response these pressures, namely the increased use of renewable energy, creates a set new challenges related supply-demand balance policy electricity system planning. This study analyses emergent problems resulting from response. These complex aspects in analysed with cross-impact model based on an expert-driven...
Since 2013, the biggest Caribbean island, Cuba, has been undertaking an energy matrix change. There is a strong political intention to replace fossil fuels by renewable and improve efficiency security of national system. By 2030, 24% electric power shall be produced from sources. Transition centralized fuel fired system towards distributed generation based requires changes conventional planning design procedures as well physical structures This paper introduces three analysis axis: Scenario...
Due to new emission regulations, coverage of monitoring requirements extends boiler classes. In Europe, Industrial Emission Directive brings 15-50 MW boilers under the directive in special cases, so inexpensive NOx tools are appreciated. This paper presents models estimate two similar natural gas fired municipal hot water boilers. The utilize online process measurements also available relatively simple set-ups. context, performance linear regression model and nonlinear neural network...
In European Union green hydrogen production is regulated to guarantee that transition energy will really have positive effect on the mitigation of climate change, and integration economy existing system be as smooth possible. However, these regulations complicate optimal design operation production. Requirement about one-hour temporal correlation between contracted variable renewable electricity forces invest in overcapacity electrolyzers high-capacity storages buffer supply flow end use...
The overall objective of the study is to improve usability and efficiency desulphurization processes by providing assistance for plant operators indicating arising issues. This paper introduces an indirect method monitor spraying in semi-dry processes, which based on energy balance first principle models. can e.g. be used estimate flue gas exit temperature rector, main control variable process, slurry flows reactors. indicates what should if functioning properly. was tested with process data...
Today total environmental impacts of power production are a subject emerging interest. Operation plants presents direct and indirect to the environment. Direct consist instant emissions due operation originated from transportation fuels waste handling. The monitored with Continuous Emission Monitoring Systems (CEMS) but Life Cycle Impacts (LCI) typically assessed only once during design phase process properties such as applied combustion technology fuels. This paper introduces procedure for...
Micro-size hydro power plants are commonly used at remote areas to supply islanded AC micro-grids. A typical way control grid frequency is manipulate active dissipated in ballast loads by AC/AC converters. However, conventional asymmetrically switched thyristor controlled converters consume reactive degrading the factor generator output and transmission efficiency. In this paper operation of a symmetric angle switched, bridged three-phase rectifier three single-phase rectifiers connected...
In this work, the operating cost of CHP production is reduced by creating optimization model to schedule operation heat storage. The objective function targets minimize costs and maximize profits electricity production. To implement in practice automate operation, storage every normal situation with its real-life process constraints modelled. time-variant non-linear system detailed enough, a MILP (Mixed Integer Linear Programming) was selected used create piecewise linear system. A sliding...
