Energy Storage Systems have recently become matters of significant interest to mitigate various existing andimminent issues of power systems. Among different storage technologies, Power-to Gas (PtG) is consideredthe most innovative technology to store and transport energy. The development of PtG technologies createspotential interactions between the electrical and gas sectors, which could lead to new options forlarge-capacities utility scale energy storage. In PtG, electrical energy is used to form hydrogen or syntheticnatural gas (SNG), which can then be injected, transported, stored, and used at a later time in the gas networkfor heating, transportation, and/or electrical generation.In this project, a model will be developed for the optimal design and operation scheduling of PtG. Theobjective of the model is to maximize the net revenue of PtG through its optimal dispatch for the combinedpurposes of producing renewable hydrogen/SNG fuel and providing power grid services. The services willinclude frequency regulation, spinning or Operating Reserve (OR), and Demand Response (DR). Also, thecontribution of PtG in balancing the generation and demand (ramping down) for long durations during periodsof surplus in baseload generation and/or high penetration levels of intermittent renewable energy resources willbe evaluated. To determine economic competitiveness of PtG compared to other energy storage systems,revenues from the sale of hydrogen and participation in wholesale electricity markets will be compared to thecapital cost and operating expenses over the lifetime of the PtG equipment.

近年来，储能系统已成为缓解电力系统中各种现有和即将出现的问题的重要问题。在不同的存储技术中，电力到天然气（PtG）被认为是最具创新性的存储和传输能源的技术。PtG技术的发展在电力和天然气部门之间创造了潜在的相互作用，这可能会为大容量公用事业规模的能源存储带来新的选择。在PtG中，电能被用来形成氢气或合成天然气（SNG），然后可以被注入、运输、储存，并在天然气网络中用于加热、运输和/或发电。本课题将建立PtG的优化设计和运行调度模型。该模型的目标是通过其最优调度实现PtG的净收益最大化，以生产可再生氢/煤制天然气燃料并提供电网服务。这些服务将包括频率调节、旋转或运行储备（or）和需求响应（DR）。此外，在基本负荷发电过剩和/或间歇性可再生能源的高渗透水平期间，PtG在平衡发电和需求（下降）方面的长期贡献将被评估。为了确定PtG与其他储能系统相比的经济竞争力，将把氢气销售和参与批发电力市场的收入与PtG设备使用寿命内的资本成本和运营费用进行比较。
