In order to improve the investment accuracy of power grid projects, this paper takes distribution network investment as the research object, and proposes a distribution network precision investment method based on a three-level strategy of region, power supply grid, and power supply unit. Firstly, building a precise investment index system for the investment scale of the regional distribution network, and calculate the investment situation through the precise investment calculation formula of the regional distribution network. Secondly, building a time sequence evaluation system for the overall construction of the power supply grid of the distribution network, and then study the prioritization method based on investment projects. The time sequence method for the overall construction of the power supply unit of the distribution network and the multi-objective optimization precision investment method based on the target grid framework. Finally, the effectiveness and operability of the above precision investment method are verified through empirical application.

Arithmetic Coding completely bypasses the traditional coding paradigm that replaces an input symbol by a specific code. Arithmetic coding represents a stream of input symbols by a single codeword. The modelling paradigm is a key aspect in effective data compression. In this paper we present an adaptive higher order Arithmetic coding scheme using the Prediction by Partial Match (ppm) algorithm as well as a framework for the comparison of the different compression techniques. Simulation study conducted with this framework shows that compressive effectiveness and implementing complexity increases as the order increases but above a certain order there is no gain in compression with increasing costs.
