Renewable energy hydrogen production technology is an effective way to improve the utilization of renewable energy and alleviate the problem of wind and light abandonment. However, there are many challenges in the system structure design and "Source-Load-Storage" coordination control strategy for large-scale, megawatt-scale renewable energy hydrogen production. In this paper, a hybrid wind-solar-energy storage hydrogen production system based on Medium Voltage Direct Current (MVDC) structure is proposed. HOMER software is used to plan and study the storage capacity to achieve longterm power balance and matching of the system. In addition, A decentralized coordinated control energy management system with active power following and state of charge (SOC) recovery capability is proposed and implemented for transient power regulation. An electromagnetic transient simulation was established in PSCAD/EMTDC, and semi-physical experiments were designed using StarSim to verify the effectiveness of the control strategy. Theoretical analysis and experiments show that the island MVDC network with decentralized coordinated control has technical feasibility in realizing hydrogen production from renewable energy in the 20MW level class. In addition, the power consumed by the load can realize the seconds level tracking of the output power of renewable energy.

“…Unlike the grid-connected mode, the main aims 39,40 of the stand-alone operation of VSWTs are to construct robust AC voltage in the passive network independently and maintain the power balance between the wind generations and the local loads. Moreover, the demand response [41][42][43] is more preferred in stand-alone microgrids to reduce the operation costs 41 and avoid the possible risk of WT tripping off due to the limited wind energy.…”

“…Several planning and operation challenges have had to be confronted to get to this point and others remain to reach higher penetrations [7]. Many of those challenges relate to the variable nature of the resource of wind and solar but other challenges relate to the inverters used to interface wind, solar and battery systems to the grid [8]. These are known as inverter-based resource (IBR) or converter interfaced generation (CIG).…”

Inverter-Based Resources (IBR) possess dynamics which are significantly different to those of synchronousgenerator-based sources and as IBR penetrations grow the dynamics of power systems are changing. The paper discusses the characteristics of the new dynamics and examines how they can be accommodated into the long-standing categorisations of power system stability in terms of angle, frequency and voltage stability. It is argued that inverters are causing the frequency range over which angle, frequency and voltage dynamics act to extend such that the previously partitioned categories are now coupled and further coupled to new electromagnetic modes. While grid-forming (GFM) inverters share many characteristics with generators, grid-following (GFL) inverters are different. This is explored in terms of similarities and differences in synchronisation, inertia and voltage control. The concept of duality is used to unify the synchronisation principles of GFM and GFL inverters, and thus is established the generalised angle dynamics. This enables analytical study of GFM-GFL interaction which is particularly important to guide the placement of GFM apparatuses and is even more important if GFM inverters are allowed to fallback to GFL mode during faults to avoid over-sizing to support short-term overload. Both GFL and GFM inverters contribute to voltage strength but with marked differences, which implies new features of voltage stability. Several directions for further research are identified including (i) extensions of nonlinear stability analysis to accommodate new inverter behaviours with cross-coupled time-frames. (ii) establishment of spatialtemporal indices of system strength and stability margin to guide the provision of new stability services and (iii) datadriven approaches to combat increased system complexity and confidentiality of inverter models.
