The unpredictability of renewable energy systems can affect the stability electricity grid, causing voltage and frequency imbalances. In this work, a suitable methodology based on peer-to-peer scheme applied to communities is developed implemented in simulation tool useful for investigating management strategies decision-making aims. model discretizes community its users into multiple control volumes, taking account various technologies. It incorporates balances individual as well entire community, considering prosumers, consumers, storage systems, electric vehicles. Moreover, enables exploration different solutions grid regulation optimization distributed resources. Additionally, predict demand one day ahead, facilitating organization availability minimize interactions flatten demand. objective functions, including self-consumption, self-sufficiency, grid-balancing factors, evaluate performance communities. To show capability model, it will be adopted optimize an investigated community. As result, increase self-consumption from 59.4 83.9 MW h/year achieved. Furthermore, balancing was achieved by guaranteeing non-fluctuating load providing 1.46 7.71 upward downward regulation. These findings illustrate positive impact dispatching integration sources importance further studying topic ensure stability.

With the deregulation and urgent necessity of decarbonizing electricity sector, end users have been empowered to actively partake in operation system. In this context, energy communities arise as a regulatory framework that allows aggregating group domestic consumers (or prosumers) order share own resources such storage or photovoltaics. However, collective assets should be properly designed exploit them an optimal way well avoid oversizing components, which may result higher expenditures economically harmful. This new paradigm calls for developing proper computational tools optimally planning operating communities. paper, novel tool photovoltaic arrays cooperative is developed. problem encompasses continuous binary variables, are evaluated over long time horizons characterized through representative sets. These features make computationally costly even unaffordable average machines. To overcome issue, solution strategy based on multi-cut Benders' decomposition The proposal exploits particular structure multi-year produce dense cuts strategies rely multiple benefits, while optimization including long-time parameters (such panel degradation) intuitive way. approach tested number scenarios, comparing it with traditional method without applying decomposition. Results reveals original intractable becomes manageable by machines when proposed technique, thus demonstrating its practicability importance. addition, results obtained serve highlight importance increasing local generation communities, reduce dependency grid reducing total cost users. particular, project reduces 19 % our case study. Other aspects also highlighted, photovoltaics increase exportable capacity community observing increment 96 sense, developed valuable planners, allowing take decisions pursuing improve economy efficiency entire community.

Renewable energy communities (RECs) are considered a promising tool for putting the citizens at center of transition, while also promoting self-sufficiency coming from local resources and decarbonization through high penetration renewables. A key challenge when operating RECs is represented by number decision variables to consider depending on type community participants distributed technologies, considering associated uncertainties. Moreover, monetarization shared in benefitting residential users crucial. The contribution this paper present an innovative stochastic linear programming model optimizing sharing maximize revenues with incentives as established Italian regulation. REC under study consists condominium PV plant installed rooftop, air conditioning battery storage systems each apartment. problem find optimal control strategies batteries 15-minute time-step, which expected revenue meeting users' comfort requirements preventing bills increasing. Numerical results demonstrate effectiveness optimization related assets. combined optimized both allow finding best performance terms maximization shared. In latter case, total increases 59.7 %, 38.7 % 12.6 compared baseline case no control, only, respectively.

The European Union defined the ambitious carbon-neutrality goal for 2050. Such a transition must be done gradually to avoid huge investments; therefore, medium-term energy planning of supply systems performed properly considering both economic and environmental aspects. Sector coupling measures aid achieve this target, although they require remarkable financial investment. This paper presents an innovative methodology university campus "Marche Polytechnic University" located in Italy towards carbon neutrality, i.e., 50 % emissions reduction by investment is multi-carrier local community with multiple technologies such as photovoltaic, combined heat power, gas-fired boilers, absorption, electric chillers that satisfy end-users' demand. A different mix installed new (e.g., storage or hydrogen) are investigated through Calliope framework. case studies present economic-based optimal scenario typical year planning, guaranteeing same reduction. Results underline importance exploiting synergies among carriers essential role i) renewables additional 3.3 MW photovoltaic installed), ii) batteries capacity 7 MWh, (iii) sector technologies.

The Internet of Energy (IoE) is a topic that industry and academics find intriguing promising, since it can aid in developing technology for smart cities. This study suggests an innovative energy system with peer-to-peer trading more sophisticated residential storage management. It proposes community strategy includes household customers nearby installations. Without constructing new energy-producing facilities, users consume affordable renewable by exchanging the pool. pool purchase any excess from consumers sources sell price higher than feed-in tariff but lower going rate. pricing power based on real-time link between supply demand to stimulate local trade. Under this structure, cost electricity may vary depending retail price, number consumers, amount energy. maximizes advantages utilization A Markov decision process (MDP) depicts recommended maximize consumer advantages, increase utilization, provide optimum option process. reinforcement learning technique determined best MDP exchange fuzzy inference system, which takes into account infinite opportunities process, enables Q-learning be used continuous state space problems (fuzzy Q-learning). analysis suggested demand-side management successful. efficacy advanced assessed quantitatively comparing before after deployment proposed system.

Renewable energy communities (RECs) have been gaining momentum around the world, as a way to promote sustainable development and combat climate change. These are typically composed of individuals, businesses, organizations that come together invest in use renewable sources, such solar, wind, hydraulic power. This article focuses on benefits bring territory through diffusion systems, tackling different issues like local depopulation, increasing prices, lack jobs, while reducing greenhouse gas emissions improving air quality. The novelty this lies results from first-of-its-kind national call within Next Appennino program, part National Complementary plan, aimed at formation proliferation RECs area severed by 2009 2016 earthquakes Italy, add social, environmental, value reconstruction territory. data refer municipality Castelraimondo Unione Montana dei Monti Azzurri (a consortium mountain municipalities), both located Marche region. Analysis consumer prosumer needs, well quantification exploitable production new generators installed, showed total 6.134 GWh/year can be shared community.
