A Co-simulation platform for power and gas distribution networks

The electric power system is moving rapidly towards an increased penetration of renewable energy resources. The new power to gas (PtG) technology has been recently introduced as a means to prevent renewable generation curtailment and to store any excess of renewable energy production during off-peak periods. This paper proposes a methodology for simultaneously studying the combined system flow of both power and gas distribution networks. An integrated grid comprising a 33-bus power gird and a small gas grid has been presented for testing the proposed methodology. The connection between the power grid and the gas grid is made through buses where PtG or GPG (gas-fired power generation) stations are located. Simulation results performed on Matlab are also presented to demonstrate the effectiveness of the proposed methodology.
