“…Scholars from many countries have studied the integration of CAES into CCHP microgrids. A CAES study conducted in 1976 at the Pacific Northwest Laboratory in Washington highlighted the benefits of abandoning fossil fuel refueling from a technical and economic perspective 4 . There has been a proposal in the literature 5 for a hybrid renewable energy CCHP system based on CAES that will improve its energy efficiency and renewable energy consumption.…”

Compressed air energy storage (CAES) systems have energy interfaces for multiple forms of energy, such as cold, heat, and electricity, and can therefore be combined with combined cooling, heating, and power (CCHP) microgrid applications, thus allowing both systems to fully utilise their respective advantages. However, the principle of multi energy coupling of CAES itself is complex, and the combination with CCHP microgrid makes the system architecture and technical implementation of the new system produce a lot of technical problems. Therefore, this report presents control strategies for CAES connected to the CCHP microgrid. Thus, the stable operation of the system can be achieved, and the supporting theory and practical application guidance can be provided to promote the development of CAES and combined CCHP microgrid. Firstly, the basic structure of CAES and CCHP microgrid is described, and thermodynamic models of key components are established. In the meantime, analyze the operation mechanism of internal combustion engine generator, wind turbine, photovoltaic and other energy supply components in CCHP microgrid system. The mathematical models suitable for optimal control are established. Through the above analysis model, it can provide a strong basis system characteristic analysis and optimal control. Secondly, the efficiency of the CAES system, the state and power of the storage, and the generation efficiency of the internal combustion generator are analysed. Finally, a two-level optimisation model is proposed, where the upper level is used to solve the optimal storage pressure initial value for the CAES system cycle. According to the characteristics of the compressed air energy storage system, NSGA-II is used to solve the output scheduling optimisation problem in the lower level with economy, environmental protection and energy saving as the unobjective under the condition of determining the optimal storage initial value. The simulation results show that the proposed control strategy is reasonable and feasible.

“…As observed by Gunnarsdottir et al, [3], countries, companies, and various organizations were encouraged to develop sustainable development indicators that would reason and validate decision-making at different levels three decades ago. Mak [4] acknowledges the performance indicators as being an important tool to track the evolution of strategies, policies, and decisions. Throughout the years, many studies have analyzed SED indicators.…”

The energy sector is experiencing various transformations. Simultaneously, merger and acquisition (M&A) activities in the sector are surging globally. Extensive research has focused on and analyzed M&As from the perspective of acquirer- and target-level financial performance. In comparison, a significantly lower number of studies have analyzed the macroeconomic impact of M&A activities. The field of and interests in sustainability have also been expanding in recent decades. Sustainable development goal 7 (SDG7), which calls for “affordable, reliable, sustainable and modern energy for all” by 2030, is among other sustainable development goals that were established by the UN (United Nations). However, the synthesis of indicators for measuring sustainable development and M&A performance remains a relatively vaguely explored field. Here, we perform SALSA (search, appraisal, synthesis, and analysis) and analyze which M&A and sustainable development performance indicators may be used when analyzing M&A within the energy sector. The employment of an eligible set of indicators measuring sustainable development and M&A performance may be used by practitioners, governments, and scholars for the purpose of monitoring, tracking, and the communication of the progress. The results imply that most popular sustainability measurements are indicators for sustainable energy development (ISED). There is a growing number of studies focusing on and applying country-specific methodologies. The measurement of M&A and sustainability performance faces difficulties in practice implementation due to a lack of availability of data, information, and databases, etc.
