摘要

This paper introduces a module-based approach to modelling and controlling electricity infrastructure with a high penetration of distributed renewable energy resources. Each energy-converting component is defined as a module and is represented in terms of its local variables and the interaction variables between the module and the transmission network. The structure of the electricity infrastructure is preserved in the proposed dynamical model. Therefore, it is possible to specify the performance subobjectives of each module for a given range of variations in interaction variables and to ensure that the local subobjectives are met through multidirectional distributed sensing and actuation. This approach provides a systematic means of analysing the infrastructure dynamics with increasing penetration of distributed renewable energy resources such as wind and solar. Sufficient conditions on modules and network specifications are derived under which the system-wide dynamics are stabilised. Based on these conditions, an interactive communication protocol between the modules and system operator could be implemented for distributed stabilisation. An IEEE 14 bus system is used to illustrate the concepts put forward.
