Forecasting of large-scale renewable energy clusters composed of wind power generation, photovoltaic and concentrating solar power (CSP) generation encounters complex uncertainties due to spatial scale dispersion and time scale random fluctuation. In response to this, a short-term forecasting method is proposed to improve the hybrid forecasting accuracy of multiple generation types in the same region. It is formed through training the long short-term memory (LSTM) network using spatial panel data. Historical power data and meteorological data for CSP plant, wind farm and photovoltaic (PV) plant are included in the dataset. Based on the data set, the correlation between these three types of power generation is proved by Pearson coefficient, and the feasibility of improving the forecasting ability through the hybrid renewable energy clusters is analyzed. Moreover, cases study indicates that the uncertainty of renewable energy cluster power tends to weaken due to partial controllability of CSP generation. Compared with the traditional prediction method, the hybrid prediction method has better prediction accuracy in the real case of renewable energy cluster in Northwest China.

In the modern world, attention to the use of renewable energy sources (RES) is increasing. This is primarily due to significant investments in the exploration and development of new oil and gas fields, the approaching threshold of exhaustion of these energy resources and, as a result, the end of the era of cheap oil. In addition, the use of these non-renewable energy sources is largely associated with an increase in carbon dioxide emissions into the atmosphere and an aggravation of environmental problems. According to the energy development strategy of the European Union, energy cluster projects are designed to form and develop ties between the countries. The European Union clusters focus on the following areas: energy, nutrition and health, marine and other industries. The energy cluster includes: wind energy, biomass energy, bioenergy conversion, offshore wind energy, innovative energy ecosystem. The energy cluster of the European Union unites energy companies, promoting the integration of science and technology, creating conditions for the development of competition and cooperation between enterprises in commercial activities. For many years, clusters have been the leading form of providing for regions in the world. And the field of renewable energy is no exception here. We emphasize that this area has It has a pronounced innovation orientation and is able to become a locomotive of innovative processes in Ukraine. Forming and developing clusters in the field of RES, the regions of Ukraine can significantly accelerate their own innovative development and modernize the regional economy. Therefore, the study of foreign experience in the functioning of such clusters is extremely relevant. The high capital intensity of innovative processes in the electric power industry, combined with the significant investment potential of domestic energy companies, make it possible to consider the industry as one of the largest customers for the creation of innovative technologies. The activation of these processes in the energy sector determines the need for systematic management of the joint development of energy enterprises and related industries and areas of activity. The implementation of this approach should be facilitated by the formation and development of energy clusters. The article examines the foreign experience of creating such innovative structures in the industry.

Worldwide policy referring to global warming and air pollution assumes several main guidelines, in which Renewable Energy Sources (RES) usage simultaneously with limitation of fossil fuels in energy production seems to be a major goal. Nowadays, the continuous growth of RES usage within final energy consumption is becoming an obvious part of many country’s development. Adding to that relentless pursuit for improvement of building energy efficiency results in prediction, that in nearest future one should expect the development of advanced city-scale areas constituting an Energy Cluster. The paradigm of Energy Cluster (EC) allows us to define an energy flexibility neighbourhood. This article presents the results of energy analysis of a model neighbourhood of single-family houses with possible usage of RES. The neighbourhood constituting an EC was defined considering the Polish household sector statistical study. The analyzed area consists of representative single-family houses of Poland, characterized by different built periods, building shape and geometry as well as building enclosure parameters. Within the analysis, a detailed examination of a defined EC was performed by means of TEAC – computer tool developed by authors. TEAC is based on the results of energy simulations obtained by means of Energy Plus software and Artificial Neural Network (ANN) usage. Artificial Intelligence (AI) was used for energy demand predictions of buildings. Among possible RES a detailed analysis of solar and wind energy usage was performed. As a result, we obtained an hourly energy demand space- and time distribution, RES outputs, ecological analysis concerning greenhouse gasses emission and profitability analysis of proposed modernizations for the neighbourhood.

Clusters are an organisational and economic phenomenon. This paper attempts to answer what an energy cluster actually is and whether it meets the requirements of a cluster in the classical approach of economic sciences. The Act of 20 February 2015 on renewable energy sources (Ustawa OZE 2015) introduced the concept of an ‘energy cluster’. It was aimed at, among others, increasing energy security and environmental protection through an efficient use of renewable energy sources. In the literature on the subject, there is no single universally applicable definition of a cluster, it can only be considered in its various aspects. The concept of a cluster has so many applications, associations and meanings that in many respects it has become a ‘chaotic idea’ due to flattening and equalising different types, processes and spatial scales of economic location within one universal concept. However, the main doubt concerns the very definition of a cluster. The paper considers the organisational attributes of clusters, based on the analysis of the following aspects: a) Cluster in historical terms. Overview of cluster and network definitions: i. Overview of cluster definitions ii. Overview of network structure definitions b) Energy cluster. Forms of interorganisational relations and the typology of energy clusters i. Forms of interorganisational relations in an energy cluster ii. Energy cluster against in relation to organisational network typology iii. Energy cluster as a form of company network – common features and differences c) An attempt in characterisation and definition of an energy cluster.

The article attempts to theoretically analyze the concept of clusters, in particular energy clusters. The paper presents the economic evolution of the cluster theory and the current Polish approach to energy clusters. Cluster structures in Poland have been presented against a background of European experiences. It was found that the current progression of globalization prompts for saving measures, especially in the energy sector, which drives the operation of economies. The way to meet EU requirements regarding the increased share of renewable energy sources and consumption limitation of conventional resources may be distributed energy based on the actions of prosumers, which is undoubtedly manifested in energy clusters. An incentive to create energy clusters are competitions for projects supporting cluster initiatives announced by the National Fund for Environmental Protection and Water Management as the Implementing Institution under the Infrastructure and Environment 2014-2020 Operational Programme. Among 66 entities awarded the Pilot Energy Cluster Certificate, the largest number of energy clusters is located in the Mazowieckie Voivodship (10), and the least in the Świętokrzyskie Voivodship (1). Barriers to the creation of energy clusters most often result from a lack of financing and poorly defined central regulations concerning the energy and renewable energy sector in Poland.
