This article focuses on realizing integrated power balancing (IPB) with principles of electricity market under unified national electricity market environment. Firstly

integrated power balancing security-constrained unit commitment (IPB-SCUC) mechanism is proposed by mathematically combining IPB mechanisms and SCUC principles. The framework incorporates an ancillary benefit and cost calculation method

a cost allocation scheme

and a differential contrast mechanism

systematically constructing an improved IPB mechanism fit for unified national electricity market. With the proposed IPB mechanism

power balancing zones remain the basic units of the power balancing procedure

and their boundaries are widely and deeply opened in order

realizing unified optimization and dispatching of power balancing resources over the whole power system at market-oriented mode. Secondly

using the proposed IPB mechanism as the core engine

the universal methods of dispatching the entire system’s resources under electricity market environment are proposed to systematically solve problems such as transmission channels’ constraints

power supply gaps

and renewable energy consumption. The dispatching behaviors’ benefit and cost over IPB are quantitatively estimated with value

realizing the unification of electricity current and value current. Lastly

examples based on actual operational data validate the theoretical analysis and demonstrate its practical value.
