Demand-supply Analysis Model with Energy and Balancing Capacity Exchange through Interconnection

Abstract

Under the anticipated high penetration of variable renewable energy generation such as photovoltaic and wind generation, the issue of supply-demand balancing capability should be evaluated and considered in a future power system including the traditional and innovative balancing measures such as traditional centralized generation, generation curtailment of variable renewable generation, demand activation and energy storage and enhanced use of interconnection. Under the situation, a tool for a long-range power system supply-demand analysis and asset optimization should have the capability to evaluate the balancing capability and balancing counter measures.

This paper presents a new methodology for a long-range power system demand-supply analysis and asset planning model with a set of traditional and innovative balancing models featured by the model of import and export of balancing capability between interconnected power systems.
