How to define the target framework of incremental allocation planning

Abstract: on the basis of smart energy distribution, with the implementation of various operation modes and marketing strategies, all relevant parties in incremental distribution will gradually participate. Everyone is for me, everyone is for everyone. The supplier selection of common body structure will inherit and develop the "main manufacturer supplier" model and the cooperative position of "risk sharing, benefit sharing" to create a smart ecological platform based on interconnected thinking and sharing economy

in order to implement the spirit of several opinions of the CPC Central Committee and the State Council on further deepening the reform of the power system (Zhong Fa [2015] No. 9), encourage and guide social capital to invest in incremental distribution business, and in accordance with the relevant provisions of the administrative measures for the orderly liberalization of distribution business, at the end of November 2016, the national development and Reform Commission The National Energy Administration issued the notice on standardizing the pilot reform of incremental distribution business (fgjt [2016] No. 2480), and identified the first batch of 105 pilot projects. According to the regulations, these pilot projects should be fairly open to market entities that meet the conditions of ball screws, and the project owners should be determined through open, fair and fair selection through market-oriented methods such as bidding, so as to clarify the project construction content, construction period, power supply scope and sign an agreement. In order to ensure the smooth implementation of the bidding work, the energy management department of the local government needs to prepare the incremental distribution planning of each pilot project in advance and incorporate it into the local distribution planning. Compared with traditional distribution planning, what should the target framework of incremental distribution planning look like? The following will give a rough target framework based on national policies and past experience

first, incremental distribution should be relatively independent local electricity

according to the administrative measures for orderly opening up distribution business, incremental distribution in principle refers to local electricity such as 110 kV and below voltage level electricity and 220 (330) kV and below voltage level Industrial Park (Economic Development Zone). In the same distribution area, only one company can have the distribution operation right, and the distribution operator shall not engage in distribution business beyond its distribution area. That is, from the policy level, in order to avoid repeated construction and prevent cross power supply, incremental distribution should be a relatively independent local power. At the same time, from the technical level, in order to ensure the safe operation of incremental distribution and transmission, avoid the partition and piecemeal operation of incremental distribution due to technical requirements such as electromagnetic loop disconnection, and make the incremental distribution energy have a complete network of unified allocation, operation and management, It is also required that the incremental distribution should preferably be a relatively independent local power with a "green" trend, and maintain a single point parallel with the transmission during normal operation. Therefore, in the incremental distribution planning, we should avoid the conventional distribution planning idea of nearby access and piecemeal operation, but reasonably plan the power supply voltage level according to the load demand of the incremental distribution power supply range, and try to form a relatively independent power on the highest voltage level

second, incremental distribution should be source load unified intelligent distribution

in the "management measures for orderly opening up distribution business", distribution operators can not only provide conventional power supply and distribution related businesses, but also provide value-added services for all kinds of users with compensation, and encourage the development of renewable energy power generation for the purpose of nearby consumption in incremental distribution and the combined cooling, heating and power supply that promotes the cascade utilization of energy. That is, according to the different resource endowment and energy demand of the power supply area, there will be many types of distributed power sources such as photovoltaic, wind power, biomass, geothermal, combined cooling, heating and power supply, as well as various types of energy storage equipment such as energy storage batteries, ice storage, electric vehicles, etc. in the incremental distribution, the incremental distribution will be different from the conventional distribution, but a typical intelligent distribution. Therefore, in the incremental distribution planning, we should make a reasonable distributed power planning and determine its initial access voltage level according to the resource situation and energy supply demand of the power supply area, then plan the substation scale and corresponding group scheme of each voltage level, and finally determine the incremental distribution plan according to the power supply shortage and reserve capacity demand

third, incremental distribution should be a smart energy distribution with comprehensive supply of multiple energies

distribution operators can not only provide value-added services related to electricity such as rational energy use, energy conservation, safe power use, optimized power use, demand response, but also provide users with intelligent integrated energy services such as power generation, heat supply, power supply, gas supply, water supply, etc. That is, on the basis of intelligent power supply, distribution and consumption, it is necessary to study the impact of comprehensive utilization, transformation and substitution of different energies on the distribution scheme, recommend the optimal combination and utilization scheme of various energies in the planned operation area, and put forward the relevant configuration and technical requirements of the comprehensive energy dispatching system based on this

IV. incremental distribution should be a smart ecological platform based on interconnected thinking and sharing economy

on the basis of smart energy distribution, with the implementation of various operation modes and marketing strategies, all relevant parties in incremental distribution will gradually participate, everyone for me, everyone for everyone, and jointly build a smart ecological platform based on interconnected thinking and sharing economy. Therefore, in the planning of incremental distribution, in addition to the conventional economic and financial evaluation and distribution price calculation, we should also pay attention to the value-added benefits of multi-function integration and mutual assistance of incremental distribution, and put forward the operation mode, marketing strategy and management policy suggestions that help to build a smart ecological platform based on the specific characteristics of incremental distribution
