On methodology for modelling wind power impact on power systems
There is a continuous discussion going on concerning the integration cost of wind power. The integration cost can, for example, be defined as the extra costs in the rest of the system when wind power is introduced, compared with the situation without wind power. The result of the studies depends on both parameters and the method used. The aim of this paper is to structure the methods in order to ...

As renewable electricity is added to the grid, are power markets misfiring?
When increasing megawatt-hours of variable solar and wind energy began coursing through the grid, the initial concern was an operational one—could grid reliability be maintained. But it turns out those megawatt-hours are creating market challenges, as well. What needs to be done to right the markets? Travis Kavulla, vice chairman of the Montana Public Service Commission, and Albert Cheung, ...

Reverse DC-Coupled PV+Storage
In 2018, Dynapower deployed the first DC-DC converter in a DC-coupled PV+S (PV + storage) configuration at an existing utility-scale PV+S installation. Since then, the innovative solar-plus-storage solution has gained traction due to the ability of DC-coupled PV+S to increase PV energy capture and decrease the costs as compared to AC-coupled energy storage solutions. Recent reports from IHS ...
