The frequency regulation power optimization framework for multiple resources is proposed. The cost, revenue, and performance indicators of hybrid energy storage during the regulation process are analyzed. The comprehensive efficiency evaluation system of energy storage by evaluating and weighing methods is established.
With the rapid expansion of new energy, there is an urgent need to enhance the frequency stability of the power system. The energy storage (ES) stations make it possible effectively. However, the frequency regulation (FR) demand distribution ignores the influence caused by various resources with different characteristics in traditional strategies.
As a new type of flexible regulatory resource with a bidirectional regulation function [3, 4], energy storage (ES) has attracted more attention in participation in automatic generation control (AGC). It also has become essential to the future frequency regulation auxiliary service market .
The FR cost of a regional grid is composed of the TPU costs F1 and the ES station costs F2. The TPU output P Gk z and the ES station output P Eb z are decision variables. For the TPU, the FR leads to power deviation from the optimal operating point, which in turn leads to increased wear and tear.
Our standardized container products are engineered for reliability, safety, and easy deployment. All systems include comprehensive monitoring and control systems with remote management capabilities.
