Abstract
This paper exploits different computational modelling to assess long-term static and operating reserves to multi-area systems. To deal with intermittent renewable generation and other types of technologies, this paper is proposing a flexible simulation model able to capture not only technological innovation of power system components and their electric and energetic behaviors, but also operational procedures and market agreements representations to yield planning insights about the performance of the multi-area systems. Results based on two modified test systems with a variate of generation technologies and interconnections are used to show the potential of the simulation model.
Highlights
The fast growing of the intermittent renewable generation, such as wind and solar photovoltaics, which have been watched across the countries and continental areas, has been demanding new planning and operating practices based on systemic studies [1]
The hydrothermal optimization problem was always part of the planner’s and operator’s agenda, where synchronous machine directly connected to the grid are able to offer operational systemic benefits, such as inertial response, which is an essential ancillary service to ensure short-term supply and demand balancing throughout a power system

Summary
The fast growing of the intermittent renewable generation, such as wind and solar photovoltaics, which have been watched across the countries and continental areas, has been demanding new planning and operating practices based on systemic studies [1]. The hydrothermal optimization problem was always part of the planner’s and operator’s agenda, where synchronous machine directly connected to the grid are able to offer operational systemic benefits, such as inertial response, which is an essential ancillary service to ensure short-term supply and demand balancing throughout a power system This service is assured only by synchronous generators, since they are able to provide system inertia throughout different control areas [3]. The present study relies on the planning phase of the long-term operating reserve assessment, which aims to address short-term operational reserve aspects in assessing the adequacy of power systems Concerning these perspectives, the increased usage of intermittent renewable generation and HVDC links applications has constructed the current power system, where part of these systems may be viewed as synchronous and others parts as asynchronous. This paper approaches power system analysis from these new perspectives, where computational solutions are able to capture details of interconnected systems with high penetration of intermittent renewable generation, with different agreements of support between areas, considering long-term operational reserve evaluation, are necessary
