Advantages of Sector Coupling to the Sustainable Energy Systems

After the EnergyPLAN and GenOpt have coupled together for the first time, a simulation based optimization has gained popularity in energy planning articles. The advantage of the coupling method is a synergy effect and integration of three different sectors e.g. heat, electricity and transport in comparison to a typical separated method. As a result, different technical measures cannot be applied separately for each individual sector without having impact on other coupled sectors. This impact can be demonstrated as a positive and negative cumulative effect. The cumulative effect from various technical measures applied within national energy system model may be observed only with annual simulations. Therefore, in this work this synergy effect will be explained in greater details for the first time. In this paper a parallel between individual and joined contribution of different policy goals of various technical measures applied to the national energy system model has been drawn. The conclusion aims to show the significance of sector coupling for sustainable energy planning

Smart energy systems: integration of power, heating/cooling, transport, water and waste sectors

Smart energy systems with smart infrastructure definitely represent the fundamental ingredient in the process of integration of variable generation from renewables. Even more, the steps towards smart infrastructure should be expanded to integration of energy consumption in transport, heating/cooling, water and waste sector in order to establish observability and controllability features in the integrated energy sector. These topics, with a number of complementary issues, will be elaborated through the proposed review paper. The literature overview is quite long and focus of elaboration should be concentrated on research papers with significant contributions. Topics that will be covered in this review paper include modern energy systems with high penetration of renewable energy sources and with smart grid wide applications, but also papers devoted to demand response programs (they enable distribution system operators to manage consumption in response to grid imbalances), energy storage options (including electric cars with smart electric charging), smart municipal energy grids including electricity and heat production infrastructure, power to heat technologies. Transport electrification and integration of energy consumption/production in water and waste sector will be covered in this review also with the special emphasis on increasing needs for electricity due to electrification of transport and heating sector (heat pumps,...). In this review paper open questions within smart energy system will be recognized and directions for future research and investigations will be identified. A special attention to gradual transition from the conventional energy systems towards smart multi energy systems and to corresponding research results in this field will be given

Planning of the high share of renewable sources within the Republic of Serbia Energy System: from 21.7 zo 40% - Can we reach 100%?

Planning of energy systems in Serbia has long tradition and has been regularly performed for more than 60 years. Higher shares of renewable sources have been included just recently. The costs of such insufficiently planned energy future have been seen through the significant devastation of the environment and negative economic consequences of the locking into the electricity production from lignite. The draft of the National Energy and Climate Plan for Serbia, expected in the early September, could be the first in the history official document with ambition to reach higher shares of renewable sources in energy system (up to 40%) and the first step towards decarbonisation, and way forward to open negotiation with EU regarding energy sector. The first steps could be switching from small hydro to small PV systems all across the countries households, additional wind production, usage of large hydro potential, but it must be achieved through sectors coupling approach. In order to rich 80% renewable energy system and decarbonize to 25% of current level, the 30 GW of PV and 10 GW of wind have to be integrated through flexibilization of demand, flexible power plants and pumped hydro plants, heat pumps in the district heating, electrification of the transport, increase of the interconnection, and use of hydrogen in industry, transport and heating as well as firing biomass instead of lignite. The 100% renewable energy system for Serbia with ambition of Denmark or Spain is feasible, due to resource availability, energy efficiency measures, and moderate increase in consumption contrary to leading industry nations of G8 and Chin

National Energy and Climate Planning in Serbia: From Lagging Behind to an Ambitious EU Candidate?

Just in the immediate neighbourhood of the European Union (EU), the Republic of Serbia, one of the Western Balkan (WB) EU candidate countries, is lagging behind in the process of energy transition regardless of technological advances and policy instruments available. The EU created a momentum for energy transition acceleration with the European Green Deal, which has been forwarded to the WB through the Energy Community secretariat in the form of the Green Agenda; generally speaking, response in the form of National Energy and Climate Plans (NECPs) is expected in the short term. The Republic of Serbia’s Low Carbon Development Strategy with Action Plan (LCDSA) and the current Energy Strategy will be analysed, commented on, and improvements will be suggested for the acceleration of energy transition, based on the newest findings from the simulation-based optimization techniques using the sector coupling approach to achieve ambitious variable renewable energy shares. The motivation of this research is to provide decision makers in Serbia with the best available insights regarding sustainable energy system planning tools and possible shortcuts for delayed planning of activities. In addition, the purpose is to improve Serbia’s chance of benefitting from adoption of these strategies in the country’s faster transition towards EU membership. The research compares two scenarios to illustrate a possible policy shift from small hydro power plants to photovoltaics (PV). A further increase in PV and wind power plants has been simulated using the EnergyPLAN to achieve expected scenarios of 40% renewable energy share and some more ambitious ones—up to 80%, which is realistic only with the sector coupling approach
