This paper deals with the assessment of the impact that the recent National Energy and Climate Plan (NECP) will have on the Greek power system resource adequacy and operation. A thorough long-term scenario-based analysis for the next decade (2021–2030) has been conducted in order to investigate the evolution of the electricity generation mix, the capacity and flexibility adequacy of the power system as well as the economic viability of various fast-response resources and other promising technical solutions that could be employed to cope with the implications posed by the regulatory framework. A specialized integrated software that simulates the Greek day-ahead and real-time balancing markets in a long-term horizon using finest time granularity and aiming at the maximization of the social welfare while respecting the system and various generating unit operating constraints is used. Simulation results illustrate that the gradual power system transformation in the context of energy transition that will be characterized by the minimization of carbon-intensive electricity generation and maximization of RES penetration is expected to introduce new challenges in the power system operation but will also provide new opportunities for system operators and energy companies to yield multiple benefits.

本文旨在评估最近的国家能源和气候计划（NECP）对希腊电力系统资源充足性和运行的影响。为了研究发电结构的演变，电力系统的容量和灵活性是否适当以及各种经济的可行性，已经对未来十年（2021年至2030年）进行了长期的基于情景的彻底分析。快速响应资源和其他有希望的技术解决方案，可以用来应对监管框架带来的影响。使用了专门的集成软件，该软件使用最精细的时间粒度，并在尊重系统和各种发电机组运行限制的情况下，以最佳的时间粒度在长期范围内模拟希腊的日间交易市场和实时平衡市场。仿真结果表明，以能量转换为背景的逐步电力系统转型将以减少碳密集型发电和最大RES渗透为特征，有望给电力系统运行带来新挑战，但也将提供新机遇为系统运营商和能源公司带来多重收益。
