Problems like difficult new energy consumption and insufficient peak power supply capacity exist in electric power system in Shandong province

the power system regulation capacity in Shandong province needs to be improved immediately. Energy storage is an important method to improve the regulation capacity. This article performs a current situation analysis on the existing electric power system of Shandong province and lists the main problems

from two aspects of new energy consumption and peak power supply. It researches the demand of energy storage using electrical power system planning method

puts forward that peak load regulation is the main demand of Shandong province but not the frequency modulation. Moreover

it puts forward the strategy of energy storage technology selection in such electric power system mainly consisting of fossil power plants like Shandong. Against the profit model and policy

this article gives analysis on different policies like electric power auxiliary service market

two part tariff and electric spot market

it also points out that electric spot market is the policy suitable for energy storage in the future.
