Bidding strategies for excess heat producers participating in a local wholesale heat market
Energy Reports, 2022 The heating sector of the European Union covers 80% of the household’s final energy consumption, which shows its relevance for the energy transition to the carbon neutral society, as set out in the Green Deal.

An economic study of combined heat and power plants in district heat production
Cleaner Engineering and Technology, 2020 Combined heat and power plants are playing an essential role in Finland to reduce carbon dioxide emissions in district heat production. Some of the existing district heat producers need to adopt renewable energy sources to eliminate the use of fossil ...

Abandoning peat in a city district heat system with wind power, heat pumps, and heat storage
Energy Reports, 2022 The Finnish Government has established the target of carbon-neutrality by 2035. In Finland, district heating (DH) networks in most cities rely on carbon dioxide (CO2) intensive fuels such as coal and domestic peat. This study assesses the decarbonization

Adaptive Control for Flow and Volume Regulation in Multi-Producer District Heating Systems [PDF]
IEEE Control Systems Letters, 2022 Flow and storage volume regulation is essential for the adequate transport and management of energy resources in district heating systems. In this letter, we propose a novel and suitably tailored -- decentralized -- adaptive control scheme addressing this problem whilst offering closed-loop stability guarantees.

Use of industrial excess heat to produce district cooling in tropical countries [PDF]
34th International Conference on Efficiency, Cost, Optimization, Simulation and Environmental Impact of Energy Systems (ECOS 2021), 2022 The use of fossil energy represents the largest source of greenhouse gas emissions among human activities. Thus, world population growth and rapid urbanisation require the development of energy-efficient solutions. In tropical countries,climate conditions are almost constant throughout the year and dominated by high temperatures and humidity. Therefore,

Demographic studies and constraints of buffalo farming in East Godavari district of Andhra Pradesh [PDF]
Journal of Veterinary and Animal Sciences, 2022 A survey was conducted to analyse the buffalo farming system in East Godavari district of Andhra Pradesh. The demographic studies showed that 77 per cent of buffalo farmers in the study area were of middle age. Majority of buffalo milk producers in delta

Modeling and passivity properties of multi-producer district heating systems
Automatica, 2022 We propose a comprehensive nonlinear ODE-based thermo-hydraulic model of a district heating system featuring several heat producers, consumers and storage devices which are interconnected through a distribution network of meshed topology whose temperature dynamics are explicitly considered.

Decentralized Temperature and Storage Volume Control in Multiproducer District Heating
IEEE Control Systems Letters, 2023 Modern district heating technologies have a great potential to make the energy sector more flexible and sustainable due to their capabilities to use energy sources of varied nature and to efficiently store energy for subsequent use. Central control tasks within these systems for the efficient and safe distribution of heat refer to the stabilization of ...

REGRESSION ANALYSIS OF THE ENERGY PRODUCED IN COGENERATION AND SUPPLIED TO DISTRICT HEATING SYSTEMS
Journal of Engineering Science, 2021 Currently, the district heating systems (DHSs) are intensively promoted both nationally and globally. The advantages of using these systems in urban areas compared to individual heating systems are practically indisputable. Still, it is essential that the calculation underlying the assessment of the economic profitability of the projects to connect the
