A Review of Distributed PV Operation Analysis and Demand Response Research

Abstract

Abstract. The large-scale access of the distributed photovoltaic power supply to the grid will bring great challenge to the safe operation of power grid, thus adversely affecting the further development of distributed photovoltaic. First of all, from the aspects of structure, power quality, network loss and relay protection, this paper summarizes the influence of distributed photovoltaic system on distribution network. Secondly, the distributed photovoltaic output is summarized and summarized from two aspects of distributed photovoltaic output performance analysis and output forecast. In addition, from the perspective of photovoltaic user demand response can improve the photovoltaic extinction rate, this paper also combs the analysis and research of PV user demand response modelling and electricity price mechanism. Finally, some suggestions on the key areas for future research are put up. IntroductionThe development prospect of distributed photovoltaic power generation is broad [1], it advocates the spontaneous use of electricity, the rest of the internet, there is no step-up and long-distance transportation problem, directly facing the terminal power consumers[2], in the power market reform and energy-saving emission reduction situation, has got more and more attention and development. With the increase of the distributed PV network capacity, the safe and stable operation of the power system will be influenced by the non-negligible [3]. The accurate characteristic analysis and output prediction of distributed PV are the important foundation to solve these problems and ensure the safe operation of the power grid [4]. At the same time, a lot of researches have been done on demand side participation in distribution network, the purpose of which is to adjust shifting and increase PV extinction rate by using demand response of PV users [5][6][7][8][9].Based on the influence of photovoltaic power grid on distribution network, this paper collated the research of PV power generation characteristics analysis and output prediction, and then it has further combed the research on PV user demand response, which has provided some reference for readers.
